fs: change write_begin/write_end interface to take struct kiocb *

2025-07-16T12:48:18Z

Change the address_space_operations callbacks write_begin() and write_end() to take struct kiocb * as the first argument instead of struct file *. Update all affected function prototypes, implementations, call sites, and related documentation across VFS, filesystems, and block layer. Part of a series refactoring address_space_operations write_begin and write_end callbacks to use struct kiocb for passing write context and flags.

ecryptfs: Convert ecryptfs_write() to use a folio

Remove ecryptfs_get_locked_page() and call read_mapping_folio() directly. Use the folio throught this function. Signed-off-by: Matthew Wilcox (Oracle) Link: https://lore.kernel.org/r/20241025190822.1319162-6-willy@infradead.org Reviewed-by: Pankaj Raghav Signed-off-by: Christian Brauner

ecryptfs: Convert ecryptfs_read_lower_page_segment() to take a folio

2024-11-05T16:19:59Z

All callers have a folio, so pass it in and use it directly. This will not work for large folios, but I doubt anybody wants to use large folios with ecryptfs.

ecryptfs: Use a folio throughout ecryptfs_read_folio()

2024-11-05T16:19:58Z

Remove the conversion to a struct page. Removes a few hidden calls to compound_head(). Use 'err' instead of 'rc' for clarity. Also remove the unnecessary call to ClearPageUptodate(); the uptodate flag is already clear if this function is being called. That lets us switch to folio_end_read() which does one atomic flag operation instead of two.

ecryptfs: Convert ecryptfs_writepage() to ecryptfs_writepages()

2024-11-05T16:19:58Z

By adding a ->migrate_folio implementation, theree is no need to keep the ->writepage implementation. The new writepages removes the unnecessary call to SetPageUptodate(); the folio should already be uptodate at this point.

move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23Z

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h
