2022-05-09afs: Convert afs_symlink_readpage to afs_symlink_read_folioMatthew Wilcox (Oracle)1-8/+7
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)1-7/+7
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)13-46/+48
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)22-97/+104
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(). Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org>
2022-05-09fs: Convert iomap_readpage to iomap_read_folioMatthew Wilcox (Oracle)5-18/+17
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)4-11/+10

2022-05-09fs: Introduce aops->read_folioMatthew Wilcox (Oracle)3-3/+6
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)1-37/+27
- 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)3-18/+19

2022-05-08fs: Convert is_dirty_writeback() to take a folioMatthew Wilcox (Oracle)2-20/+17

2022-05-08hfsplus: Call hfsplus_write_begin() and generic_write_end() directlyMatthew Wilcox (Oracle)3-7/+8
There is only one kind of write_begin/write_end aops, so we don't need to look up which aop it is, just make hfsplus_write_begin() available to this file and call it directly. Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org> Reviewed-by: Christoph Hellwig <hch@lst.de>

2022-05-08ntfs3: Remove fsdata parameter from ntfs_extend_initialized_size()Matthew Wilcox (Oracle)1-4/+2
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.
