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.

clean ufs_trunc_direct() up a bit...

2024-10-18T21:35:31Z

For short files (== no indirect blocks needed) UFS allows the last block to be a partial one. That creates some complications for truncation down to "short file" lengths. ufs_trunc_direct() is called when we'd already made sure that new EOF is not in a hole; nothing needs to be done if we are extending the file and in case we are shrinking the file it needs to * shrink or free the old final block. * free all full direct blocks between the new and old EOF. * possibly shrink the new final block. The logics is needlessly complicated by trying to keep all cases handled by the same sequence of operations. if not shrinking nothing to do else if number of full blocks unchanged free the tail of possibly partial last block else free the tail of (currently full) new last block free all present (full) blocks in between free the (possibly partial) old last block is easier to follow than the result of trying to unify these cases.

ufs_inode_getfrag(): remove junk comment

2024-10-18T21:35:31Z

It used to be a stubbed out beginning of ufs2 support, which had been implemented differently quite a while ago. Remove the commented-out (pseudo-)code. Signed-off-by: Al Viro

buffer: Convert __block_write_begin() to take a folio

2024-08-07T09:33:36Z

Almost all callers have a folio now, so change __block_write_begin() to take a folio and remove a call to compound_head(). Reviewed-by: Josef Bacik Signed-off-by: Matthew Wilcox (Oracle) Signed-off-by: Christian Brauner

fs: Convert aops->write_begin to take a folio

2024-08-07T09:33:21Z

Convert all callers from working on a page to working on one page of a folio (support for working on an entire folio can come later). Removes a lot of folio->page->folio conversions. Reviewed-by: Josef Bacik Signed-off-by: Matthew Wilcox (Oracle) Signed-off-by: Christian Brauner

fs: Convert aops->write_end to take a folio

2024-08-07T09:32:02Z

Most callers have a folio, and most implementations operate on a folio, so remove the conversion from folio->page->folio to fit through this interface. Reviewed-by: Josef Bacik Signed-off-by: Matthew Wilcox (Oracle) Signed-off-by: Christian Brauner
