eb->io_pages is set in read_extent_buffer_pages().
In case of readpage failure, for pages that have been added to bio,
it calls bio_endio and later readpage_io_failed_hook() does the work.
When this eb's page (couldn't be the 1st page) fails to add itself to bio
due to failure in merge_bio(), it cannot decrease eb->io_pages via bio_endio,
and ends up with a memory leak eventually.
This lets __do_readpage propagate errors to callers and adds the
'atomic_dec(&eb->io_pages)'.

In btrfs, btrfs_space_info's bytes_may_use is treated as fs used
space, as what we do in reserve_metadata_bytes() or
btrfs_alloc_data_chunk_ondemand(), so in dump_space_info(), when
calculating free space, we should also subtract btrfs_space_info's
bytes_may_use.

btrfs/073 invokes scrub ioctl in a tight loop. In subpage-blocksize
scenario this results in a lot of "scrub: size assumption sectorsize !=
PAGE_SIZE " messages being printed on the console. To reduce the number
of such messages this commit uses btrfs_err_rl() instead of
btrfs_err().

This is similar to btrfs_submit_compressed_read(), if we fail after
bio is allocated, then we can use bio_endio() and errors are saved
in bio->bi_error. But please note that we don't return errors to
its caller because the caller assumes it won't call endio to cleanup

One can use btrfs-corrupt-block to hit BUG_ON() in merge_bio(),
thus this aims to stop anyone to panic the whole system by using
their btrfs.
Since the error in merge_bio can only come from __btrfs_map_block()
when chunk tree mapping has something insane and __btrfs_map_block()
has already had printed the reason, we can just return errors in
merge_bio.

BTRFS is using a variety of slab caches to satisfy internal needs.
Those slab caches are always allocated with the SLAB_RECLAIM_ACCOUNT,
meaning allocations from the caches are going to be accounted as
SReclaimable. At the same time btrfs is not registering any shrinkers
whatsoever, thus preventing memory from the slabs to be shrunk. This
means those caches are not in fact reclaimable.
To fix this remove the SLAB_RECLAIM_ACCOUNT on all caches apart from the
inode cache, since this one is being freed by the generic VFS super_block
shrinker. Also set the transaction related caches as SLAB_TEMPORARY,
to better document the lifetime of the objects (it just translates
to SLAB_RECLAIM_ACCOUNT).

BTRFS_IOC_LOGICAL_INO takes a btrfs_ioctl_logical_ino_args as argument,
not a btrfs_ioctl_ino_path_args. The lines were probably copy/pasted
when the code was written.
Since btrfs_ioctl_logical_ino_args and btrfs_ioctl_ino_path_args have
the same size, the actual IOCTL definition here does not change.
But, it makes the code less confusing for the reader.

The code flow in btrfs_new_inode allows for btrfs_evict_inode to be
called with not fully initialised inode (e.g. ->root member not
being set). This can happen when btrfs_set_inode_index in
btrfs_new_inode fails, which in turn would call iput for the newly
allocated inode. This in turn leads to vfs calling into btrfs_evict_inode.
This leads to null pointer dereference. To handle this situation check whether
the passed inode has root set and just free it in case it doesn't.

We use read_node_slot() to read btree node and it has two cases,
a) slot is out of range, which means 'no such entry'
b) we fail to read the block, due to checksum fails or corrupted
content or not with uptodate flag.
But we're returning NULL in both cases, this makes it return -ENOENT
in case a) and return -EIO in case b), and this fixes its callers
as well as btrfs_search_forward() 's caller to catch the new errors.

It turns out that we free fs root twice, btrfs_init_fs_root() calls
free_anon_bdev(root->anon_dev) and later then btrfs_get_fs_root() cals
free_fs_root which does another free_anon_bdev() and it ends up with the
above warning.
Instead of reset root->anon_dev to 0 after free_anon_bdev(), we can let
btrfs_init_fs_root() return directly since its callers have already done
the free job by calling free_fs_root().

With btrfs-corrupt-block, one can set btree node/leaf's field, if
we assign a negative value to node/leaf, we can get various hangs,
eg. if extent_root's nritems is -2ULL, then we get stuck in
btrfs_read_block_groups() because it has a while loop and
btrfs_search_slot() on extent_root will always return the first
child.
This lets us know what's happening and returns a EINVAL to callers
instead of returning the first item.

Commit 56244ef151c3cd11 was almost but not quite enough to fix the
reservation math after btrfs_copy_from_user returned partial copies.
Some users are still seeing warnings in btrfs_destroy_inode, and with a
long enough test run I'm able to trigger them as well.
This patch fixes the accounting math again, bringing it much closer to
the way it was before the sectorsize conversion Chandan did. The
problem is accounting for the offset into the page/sector when we do a
partial copy. This one just uses the dirty_sectors variable which
should already be updated properly.

We used to allow you to set FLUSH_ALL and then just wouldn't do things like

we've lost the ability to tell, and we could end up deadlocking. So instead use
FLUSH_LIMIT in reserve_metadata_bytes in relocation and then return -EAGAIN if
we error out to preserve the previous behavior. I've also added an ASSERT() to
catch anybody else who tries to do this. Thanks,

Traditionally we've calculated the global block rsv by guessing how much of the
metadata used amount was the extent tree, and then taking the data size and
figuring out how large the csum tree would have to be to hold that much data.
This is imprecise and falls down on MIXED file systems as we can't trust the
data used amount. This resulted in failures for xfstests generic/333 because it
creates lots of clones, which explodes out the extent tree. Our global reserve
calculations were woefully inaccurate in this case which meant we got into a
situation where we did not have enough reserved to do our work.
We know we only use the global block rsv for the extent, csum, and root trees,
so just get the bytes used for these trees and use that as the basis of our
global reserve. Since these are not reference counted trees the bytes_used
value will be accurate. This fixed the transaction aborts seen with
generic/333. Thanks,

Our enospc flushing sucks. It is born from a time where we were early
enospc'ing constantly because multiple threads would race in for the same
reservation and randomly starve other ones out. So I came up with this solution
to block any other reservations from happening while one guy tried to flush
stuff to satisfy his reservation. This gives us pretty good correctness, but
completely crap latency.
The solution I've come up with is ticketed reservations. Basically we try to
make our reservation, and if we can't we put a ticket on a list in order and
kick off an async flusher thread. This async flusher thread does the same old
flushing we always did, just asynchronously. As space is freed and added back
to the space_info it checks and sees if we have any tickets that need
satisfying, and adds space to the tickets and wakes up anything we've satisfied.
Once the flusher thread stops making progress it wakes up all the current
tickets and tells them to take a hike.
There is a priority list for things that can't flush, since the async flusher
could do anything we need to avoid deadlocks. These guys get priority for
having their reservation made, and will still do manual flushing themselves in
case the async flusher isn't running.
This patch gives us significantly better latencies. Thanks,

We reserve space for the inode update when we first reserve space for writing to
a file. However there are lots of ways that we can use this reservation and not
have it for subsequent ordered extents. Previously we'd fall through and try to
reserve metadata bytes for this, then we'd just steal the full reservation from
the delalloc_block_rsv, and if that didn't have enough space we'd steal the full
reservation from the global reserve. The problem with this is we can easily
just return ENOSPC and fallback to updating the inode item directly. In the
worst case (assuming 4k nodesize) we'd steal 64kib from the global reserve if we
fall all the way through, however if we just fallback and update the inode
directly we'd only steal 4k * BTRFS_PATH_MAX in the worst case which is 32kib.
We would have also just added the extent item for the inode so we likely will
have already cow'ed down most of the way to the leaf containing the inode item,
so we are more often than not only need one or two nodesize's worth of
reservations. Given the reservation for the extent itself is also a worst case
we will likely already have space to cover the inode update.
This change will make us behave better in the theoretical worst case, and much
better in the case that we don't have our reservation and cannot reserve more
metadata. Thanks,

There are a few races in the metadata reservation stuff. First we add the bytes
to the block_rsv well after we've set the bit on the inode saying that we have
space for it and after we've reserved the bytes. So use the normal
btrfs_block_rsv_add helper for this case. Secondly we can flush delalloc
extents when we try to reserve space for our write, which means that we could
have used up the space for the inode and we wouldn't know because we only check
before the reservation. So instead make sure we are always reserving space for
the inode update, and then if we don't need it release those bytes afterward.

So btrfs_block_rsv_migrate just unconditionally calls block_rsv_migrate_bytes.
Not only this but it unconditionally changes the size of the block_rsv. This
isn't a bug strictly speaking, but it makes truncate block rsv's look funny
because every time we migrate bytes over its size grows, even though we only
want it to be a specific size. So collapse this into one function that takes an
update_size argument and make truncate and evict not update the size for
consistency sake. Thanks,

overlay needs underlying fs to support d_type. Recently I put in a
patch in to detect this condition and started failing mount if
underlying fs did not support d_type.
But this breaks existing configurations over kernel upgrade. Those who
are running docker (partially broken configuration) with xfs not
supporting d_type, are surprised that after kernel upgrade docker does
not run anymore.
https://github.com/docker/docker/issues/22937#issuecomment-229881315
So instead of erroring out, detect broken configuration and warn
about it. This should allow existing docker setups to continue
