2015-02-18NFSv4.1: Clean up bind_conn_to_sessionTrond Myklebust
We don't need to fake up an entire session in order retrieve the arguments. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
2015-02-18NFSv4.1: Always set up a forward channel when binding the sessionTrond Myklebust
Currently, the client requests a back channel or a bidirectional connection when binding a new TCP channel to an existing session. Fix that to ask for a forward channel or bidirectional. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>

Commit 411a99adffb4f (nfs: clear_request_commit while holding i_lock) assumes that the nfs_commit_info always points to the inode->i_lock.

Pull backing device changes from Jens Axboe: "This contains a cleanup of how the backing device is handled, in preparation for a rework of the life time rules. In this part, the most important change is to split the unrelated nommu mmap flags from it, but also removing a backing_dev_info pointer from the address_space (and inode), and a cleanup of other various minor bits.

2015-02-10Merge branch 'akpm' (patches from Andrew)Linus Torvalds
Merge misc updates from Andrew Morton: "Bite-sized chunks this time, to avoid the MTA ratelimiting woes. - fs/notify updates - ocfs2 - some of MM" That laconic "some MM" is mainly the removal of remap_file_pages(), which is a big simplification of the VM, and which gets rid of a *lot* of random cruft and special cases because we no longer support the non-linear mappings that it used. From a user interface perspective, nothing has changed, because the remap_file_pages() syscall still exists, it's just done by emulating the old behavior by creating a lot of individual small mappings instead of one non-linear one. The emulation is slower than the old "native" non-linear mappings, but nobody really uses or cares about remap_file_pages(), and simplifying the VM is a big advantage. * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (78 commits) memcg: zap memcg_slab_caches and memcg_slab_mutex memcg: zap memcg_name argument of memcg_create_kmem_cache memcg: zap __memcg_{charge,uncharge}_slab mm/page_alloc.c: place zone_id check before VM_BUG_ON_PAGE check mm: hugetlb: fix type of hugetlb_treat_as_movable variable mm, hugetlb: remove unnecessary lower bound on sysctl handlers"? mm: memory: merge shared-writable dirtying branches in do_wp_page() mm: memory: remove ->vm_file check on shared writable vmas xtensa: drop _PAGE_FILE and pte_file()-related helpers x86: drop _PAGE_FILE and pte_file()-related helpers unicore32: drop pte_file()-related helpers um: drop _PAGE_FILE and pte_file()-related helpers tile: drop pte_file()-related helpers sparc: drop pte_file()-related helpers sh: drop _PAGE_FILE and pte_file()-related helpers score: drop _PAGE_FILE and pte_file()-related helpers s390: drop pte_file()-related helpers parisc: drop _PAGE_FILE and pte_file()-related helpers openrisc: drop _PAGE_FILE and pte_file()-related helpers nios2: drop _PAGE_FILE and pte_file()-related helpers ...

2015-02-04NFSv4.1: Ask for no delegation on OPEN if using O_DIRECTTrond Myklebust
If we're using NFSv4.1, then we have the ability to let the server know whether or not we believe that returning a delegation as part of our OPEN request would be useful. The feature needs to be used with care, since the client sending the request doesn't necessarily know how other clients are using that file, and how they may be affected by the delegation. For this reason, our initial use of the feature will be to let the server know when the client believes that handing out a delegation would not be useful. The first application for this function is when opening the file using O_DIRECT. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>

2015-02-03pnfs: lookup new lseg at lseg boundaryWeston Andros Adamson
Before mirroring support was added, the pageio descriptor's pg_lseg was set to null when an RPC was sent. Because of this, pg_init was called at lseg boundaries with pg_lseg = NULL, and it could be set to the new lseg. Signed-off-by: Weston Andros Adamson <dros@primarydata.com>

2015-02-03nfs: count DIO good bytes correctly with mirroringPeng Tao
When resending to MDS, we might resend multiple mirroring requests to MDS. As a result, nfs_direct_good_bytes() ends up counting bytes multiple times, causing application to get wrong return results in read/write syscalls.

2015-02-03nfs41: add NFS_LAYOUT_RETRY_LAYOUTGET to layout header flagsPeng Tao
Use it to indicate that LD wants to retry layoutget. LD can set it whenever it wants the common pnfs code to return and retry pnfs path through a new layout. The bit gets cleared when client does a new layoutget, when client closes the file (ROC case), or when kernel needs to evict the inode (non-ROC case).

2015-02-03nfs/flexfiles: send layoutreturn before freeing lsegPeng Tao
Otherwise we'll lose error tracking information when encoding layoutreturn. pnfs_put_lseg may be called from rpc callbacks.

2015-02-03nfs41: introduce NFS_LAYOUT_RETURN_BEFORE_CLOSEPeng Tao
When it is set, generic pnfs would try to send layoutreturn right before last close/delegation_return regard less NFS_LAYOUT_ROC is set or not. LD can then make sure layoutreturn is always sent rather than being omitted. The difference against NFS_LAYOUT_RETURN is that NFS_LAYOUT_RETURN_BEFORE_CLOSE does not block usage of the layout so LD can set it and expect generic layer to try pnfs path at the same time.
