From: Kent Overstreet Date: Mon, 16 Jun 2025 20:13:02 +0000 (-0400) Subject: bcachefs: fsck: check_directory_structure runs in reverse order X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=3e5ceaa5bfd71ae94d736426f8a27391023182ff;p=linux-block.git bcachefs: fsck: check_directory_structure runs in reverse order When we find a directory connectivity problem, we should do the repair in the oldest snapshot that has the issue - so that we don't end up duplicating work or making a real mess of things. Oldest snapshot IDs have the highest integer value, so - just walk inodes in reverse order.
