2022-03-22Merge tag 'folio-5.18b' of git://git.infradead.org/users/willy/pagecacheLinus Torvalds
Pull filesystem folio updates from Matthew Wilcox: "Primarily this series converts some of the address_space operations to take a folio instead of a page. Notably: - a_ops->is_partially_uptodate() takes a folio instead of a page and changes the type of the 'from' and 'count' arguments to make it obvious they're bytes. - a_ops->invalidatepage() becomes ->invalidate_folio() and has a similar type change. - a_ops->launder_page() becomes ->launder_folio() - a_ops->set_page_dirty() becomes ->dirty_folio() and adds the address_space as an argument. There are a couple of other misc changes up front that weren't worth separating into their own pull request" * tag 'folio-5.18b' of git://git.infradead.org/users/willy/pagecache: (53 commits) fs: Remove aops ->set_page_dirty fb_defio: Use noop_dirty_folio() fs: Convert __set_page_dirty_no_writeback to noop_dirty_folio fs: Convert __set_page_dirty_buffers to block_dirty_folio nilfs: Convert nilfs_set_page_dirty() to nilfs_dirty_folio() mm: Convert swap_set_page_dirty() to swap_dirty_folio() ubifs: Convert ubifs_set_page_dirty to ubifs_dirty_folio f2fs: Convert f2fs_set_node_page_dirty to f2fs_dirty_node_folio f2fs: Convert f2fs_set_data_page_dirty to f2fs_dirty_data_folio f2fs: Convert f2fs_set_meta_page_dirty to f2fs_dirty_meta_folio afs: Convert afs_dir_set_page_dirty() to afs_dir_dirty_folio() btrfs: Convert extent_range_redirty_for_io() to use folios fs: Convert trivial uses of __set_page_dirty_nobuffers to filemap_dirty_folio btrfs: Convert from set_page_dirty to dirty_folio fscache: Convert fscache_set_page_dirty() to fscache_dirty_folio() fs: Add aops->dirty_folio fs: Remove aops->launder_page orangefs: Convert launder_page to launder_folio nfs: Convert from launder_page to launder_folio fuse: Convert from launder_page to launder_folio ...

2022-01-22mm: remove cleancacheChristoph Hellwig
Patch series "remove Xen tmem leftovers". Since the removal of the Xen tmem driver in 2019, the cleancache hooks are entirely unused, as are large parts of frontswap. This series against linux-next (with the folio changes included) removes cleancaches, and cuts down frontswap to the bits actually used by zswap. This patch (of 13): The cleancache subsystem is unused since the removal of Xen tmem driver in commit 814bbf49dcd0 ("xen: remove tmem driver").

Accessing the buffer will trigger a page fault, and gfs2 will deadlock trying to take the same inode glock again while trying to handle that fault.

Currently a failed allocation on sbi->upcase will cause an exit via the label free_sbi causing a memory leak on object opts. Fix this by re-ordering the exit paths free_opts and free_sbi so that kfree's occur in the reverse allocation order.

2021-09-20fs/ntfs3: Initiliaze sb blocksize only in one place + refactorKari Argillander
Right now sb blocksize first get initiliazed in fill_super but in can be changed in helper function. It makes more sense to that this happened only in one place. Because we move this to helper function it makes more sense that s_maxbytes will also be there. I rather have every sb releted thing in fill_super, but because there is already sb releted stuff in this helper. This will have to do for now.

2021-09-20fs/ntfs3: Initialize pointer before use place in fill_superKari Argillander
Initializing should be as close as possible when we use it so that we do not need to scroll up to see what is happening. Also bdev_get_queue() can never return NULL so we do not need to check for !rq.

2021-09-20fs/ntfs3: Remove tmp pointer upcase in fill_superKari Argillander
We can survive without this tmp point upcase. So remove it we don't have so many tmp pointer in this function. Signed-off-by: Kari Argillander <kari.argillander@gmail.com> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2021-09-20fs/ntfs3: Remove tmp pointer bd_inode in fill_superKari Argillander
Drop tmp pointer bd_inode because this is only used ones in fill_super. Also we have so many initializing happening at the beginning that it is already way too much to follow.

2021-09-20fs/ntfs3: Remove tmp var is_ro in ntfs_fill_superKari Argillander
We only use this in two places so we do not really need it. Also wrapper sb_rdonly() is pretty self explanatory. This will make little bit easier to read this super long variable list in the beginning of ntfs_fill_super().

2021-09-20fs/ntfs3: Use sb instead of sbi->sb in fill_superKari Argillander
Use sb instead of sbi->sb in fill_super. We have sb so why not use it. Also makes code more readable. Signed-off-by: Kari Argillander <kari.argillander@gmail.com> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
