bcachefs: bch2_str_hash_check_key() may now be called without snapshots_seen We don't track snapshot overwrites outside of fsck, so for this to be called at runtime outside of fsck we need to create it on demand, when we have repair to do. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

bcachefs: Enumerate recovery passes Recovery and fsck have many different passes/jobs to do, which always run in the same order - but not all of them run all the time. Some are for fsck, some for unclean shutdown, some for version upgrades. This adds some new structure: a defined list of recovery passes that we can run in a loop, as well as consolidating the log messages. The main benefit is consolidating the "should run this recovery pass" logic, as well as cleaning up the "this recovery pass has finished" state; instead of having a bunch of ad-hoc state bits in c->flags, we've now got c->curr_recovery_pass. By consolidating the "should run this recovery pass" logic, in the future on disk format upgrades will be able to say "upgrading to this version requires x passes to run", instead of forcing all of fsck to run.

bcachefs: Split out check_unreachable_inodes() pass With inode backpointers, we can write a very simple check_unreachable_inodes() pass that only looks for non-unlinked inodes that are missing backpointers, and reattaches them. This simplifies check_directory_structure() so that it's now only checking for directory structure loops, Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
