2023-10-23	bcachefs: New io_misc.c helpers	Kent Overstreet	1	-1/+1
	This pulls the non vfs specific parts of truncate and finsert/fcollapse out of fs-io.c, and moves them to io_misc.c. This is prep work for logging these operations, to make them atomic in the event of a crash. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23	bcachefs: Break up io.c	Kent Overstreet	1	-1/+1
	More reorganization, this splits up io.c into - io_read.c - io_misc.c - fallocate, fpunch, truncate - io_write.c Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23	bcachefs: Split up fs-io.[ch]	Kent Overstreet	1	-18/+148
	fs-io.c is too big - time for some reorganization - fs-dio.c: direct io - fs-pagecache.c: pagecache data structures (bch_folio), utility code Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23	bcachefs: Delete bch_writepage	Kent Overstreet	1	-1/+0
	Per Dave Chinner and the xfs folks, .writepage is no longer needed, and it's better not to define it if .writepages is the intended path. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23	bcachefs: fix truncate with ATTR_MODE	Kent Overstreet	1	-1/+2
	After the v5.12 rebase, we started oopsing when truncate was passed ATTR_MODE, due to not passing mnt_userns to setattr_copy(). This refactors things so that truncate/extend finish by using bch2_setattr_nonsize(), which solves the problem. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23	bcachefs: Kill bchfs_extent_update()	Kent Overstreet	1	-8/+0
	The generic IO path now handles inode updates for i_size and i_sectors - this means we can drop a fair amount of code from fs-io.c. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23	bcachefs: Convert bch2_fpunch to bch2_extent_update()	Kent Overstreet	1	-2/+0
	As before - we're moving non Linux specific code out of fs-io.c. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23	bcachefs: Split out bchfs_extent_update()	Kent Overstreet	1	-7/+7
	The next few patches are going to be more moving the logic around i_size/i_sectors updates to io.c, and better separating the Linux VFS specific code from core bcachefs code, to better support the fuse port. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23	bcachefs: Check if extending inode differently	Kent Overstreet	1	-1/+1
	In bch2_extent_update(), we have to update the inode if i_size is changing (the file is being extend) or if i_sectors is changing, but we want to avoid touching the inode if it's not necessary. Change sum_sector_overwrites() to also check if there's already data above where we're writing to - this means we're definitely not extending the file.

2023-10-23	bcachefs: Reflink	Kent Overstreet	1	-0/+19
	Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23	bcachefs: Always touch page state with page locked	Kent Overstreet	1	-2/+0
	This will mean we don't have to use cmpxchg for modifying page state, which will simplify a fair amount of code Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23	bcachefs: Initial commit	Kent Overstreet	1	-0/+47
	Initially forked from drivers/md/bcache, bcachefs is a new copy-on-write filesystem with every feature you could possibly want. Website: https://bcachefs.org Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
