H A D | subpage.h | diff e4f94347 Mon Sep 27 01:21:49 MDT 2021 Qu Wenruo <wqu@suse.com> btrfs: subpage: add bitmap for PageChecked flag Although in btrfs we have very limited usage of PageChecked flag, it's still some page flag not yet subpage compatible. Fix it by introducing btrfs_subpage::checked_offset to do the convert. For most call sites, especially for free-space cache, COW fixup and btrfs_invalidatepage(), they all work in full page mode anyway. For other call sites, they work as subpage compatible mode. Some call sites need extra modification: - btrfs_drop_pages() Needs extra parameter to get the real range we need to clear checked flag. Also since btrfs_drop_pages() will accept pages beyond the dirtied range, update btrfs_subpage_clamp_range() to handle such case by setting @len to 0 if the page is beyond target range. - btrfs_invalidatepage() We need to call subpage helper before calling __btrfs_releasepage(), or it will trigger ASSERT() as page->private will be cleared. - btrfs_verify_data_csum() In theory we don't need the io_bio->csum check anymore, but it's won't hurt. Just change the comment. Signed-off-by: Qu Wenruo <wqu@suse.com> Signed-off-by: David Sterba <dsterba@suse.com> |
