2022-05-09cifs: Convert cifs to read_folioMatthew Wilcox (Oracle)
This is a "weak" conversion which converts straight back to using pages. CIFS should probably be converted to use netfs_read_folio() by someone familiar with it. Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org>
2022-05-09btrfs: Convert btrfs to read_folioMatthew Wilcox (Oracle)
This is a "weak" conversion which converts straight back to using pages. A full conversion should be performed at some point, hopefully by someone familiar with the filesystem. Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org>

2022-05-09afs: Convert afs_symlink_readpage to afs_symlink_read_folioMatthew Wilcox (Oracle)
This function mostly used folios already, and only a few minor changes were needed. Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org>

2022-05-09fs: Convert simple_readpage to simple_read_folioMatthew Wilcox (Oracle)
This is a full folio conversion; it is prepared to handle folios of arbitrary size. Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org>
2022-05-09fs: Convert mpage_readpage to mpage_read_folioMatthew Wilcox (Oracle)
mpage_readpage still works in terms of pages, and has not been audited for correctness with large folios, so include an assertion that the filesystem is not passing it large folios. Convert all the filesystems to call mpage_read_folio() instead of mpage_readpage(). Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org>
2022-05-09fs: Convert block_read_full_page() to block_read_full_folio()Matthew Wilcox (Oracle)
This function is NOT converted to handle large folios, so include an assert that the filesystem isn't passing one in. Otherwise, use the folio functions instead of the page functions, where they exist. Convert all filesystems which use block_read_full_page().

2022-05-09fs: Convert iomap_readpage to iomap_read_folioMatthew Wilcox (Oracle)
A straightforward conversion as iomap_readpage already worked in folios. Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org>
2022-05-09fs: Convert netfs_readpage to netfs_read_folioMatthew Wilcox (Oracle)

Convert all the ->readpage documentation to ->read_folio. Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org>
2022-05-09fs: Introduce aops->read_folioMatthew Wilcox (Oracle)
Change all the callers of ->readpage to call ->read_folio in preference, if it exists. This is a transitional duplication, and will be removed by the end of the series. Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org>
2022-05-08buffer: Rewrite nobh_truncate_page() to use foliosMatthew Wilcox (Oracle)
- Calculate iblock directly instead of using a while loop - Move has_buffers to the end to remove a backwards jump - Use __filemap_get_folio() instead of grab_cache_page(), which removes a spurious FGP_ACCESSED flag. - Eliminate length and pos variables - Use folio APIs where they exist Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org> Reviewed-by: Christoph Hellwig <hch@lst.de>
2022-05-08mm/readahead: Convert page_cache_async_readahead to take a folioMatthew Wilcox (Oracle)

2022-05-08filemap: Remove obsolete comment in lock_pageMiaohe Lin
We no longer need the page's inode pinned. This comment dates back to commit db37648cd6ce ("[PATCH] mm: non syncing lock_page()") which added lock_page_nosync().

2022-05-08ntfs3: Remove fsdata parameter from ntfs_extend_initialized_size()Matthew Wilcox (Oracle)
After the last patch, Smatch reports: fs/ntfs3/file.c:168 ntfs_extend_initialized_size() error: uninitialized symbol 'fsdata'. fsdata is indeed unused. This is not new, but Smatch couldn't see it before because calls through pagecache_write_begin()/pagecache_write_end() could theoretically call any implemention of ->write_begin/write_end, some of which do use fsdata. Now that the calls are direct, Smatch can see they're never used. Fix this by simply passing NULL. While ntfs3 does pass this parameter on to generic functions, those generic functions also never dereference the fsdata parameter, so it's unnecessary to pass the address of a real pointer.

2022-05-08floppy: use a statically allocated error counterWilly Tarreau
Interrupt handler bad_flp_intr() may cause a UAF on the recently freed request just to increment the error count. There's no point keeping that one in the request anyway, and since the interrupt handler uses a static pointer to the error which cannot be kept in sync with the pending request, better make it use a static error counter that's reset for each new request. This reset now happens when entering redo_fd_request() for a new request via set_next_request(). One initial concern about a single error counter was that errors on one floppy drive could be reported on another one, but this problem is not real given that the driver uses a single drive at a time, as that PC-compatible controllers also have this limitation by using shared signals. As such the error count is always for the "current" drive.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v5.18 A larger collection of fixes than I'd like, mainly because mixer-test is making it's way into the CI systems and turning up issues on a wider range of systems. The most substantial thing though is a revert and an alternative fix for a dmaengine issue where the fix caused disruption for some other configurations, the core fix is backed out an a driver specific thing done instead.
