various recovery fixes: - fixes for the btree_insert_entry being resized on path allocation btree_path array recently became dynamically resizable, and btree_insert_entry along with it; this was being observed during journal replay, when write buffer btree updates don't use the write buffer and instead use the normal btree update path - multiple fixes for deadlock in recovery when we need to do lots of btree node merges; excessive merges were clocking up the whole pipeline - write buffer path now correctly does btree node merges when needed - fix failure to go RW when superblock indicates recovery passes needed (i.e. to complete an unfinished upgrade) various unsafety fixes - test case contributed by a user who had two drives out of a six drive array write out a whole bunch of garbage after power failure new (tiny) on disk format feature: since it appears the btree node scan tool will be a more regular thing (crappy hardware, user error) - this adds a 64 bit per-device bitmap of regions that have ever had btree nodes. a path->should_be_locked fix, from a larger patch series tightening up invariants and assertions around btree transaction and path locking state; this particular fix prevents us from keeping around btree_paths that are no longer needed. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKnAFLkS8Qha+jvQrE6szbY3KbnYFAmYdaRIACgkQE6szbY3K bnbqcA/9ETT0Jekf/V4klQmoWj9GX5nQstUz+ENABNNPL+5hld62EojiRvOW2qwU zVs7O0M59B8/+4v4KJoW+RqnLFjAF4z/Gf+/Uw9WarsHAKIxxFFFARxG93JpGqOn nGa8RSw0BaYQIdbMR0Bdacc2f0N+JkJQx956/+JV7EG5MAJqXgz00AvIuLqMZ+2t 0m9av3n0tVmstyvvGqk8pouvQjK0XUvIDYN3oiUDl7WXOAIKXDlp6yviiGnTbusq DssmIt5fdeVBq/DAk5PMNEKM9NUP+weIZW1UWPWINaicarqyV+pn2fhvLrBxVl7q zBSN3v28viaABKC8A15b2bqj3IT2WIBDoBCEi406akMao9eiVsE6is13rFkPQwQI Obhc7NNDyOPPTvX25M3tKXpr8rSGoD2qHIMMKMIBe1ZWscj6lMbmUBErwzTOAW4+ pNTvzWT2XwcS7tE8Fx50ZxcehTQl6ir0hQvjJL5JV2po8XMbdGxcImBe6xPmAa3n /XIzyglL8IvW494wjCsHxtTeOt+f8nW7BXJCrWB71UQeXIXq4b9FADOwWtlGTnxJ 6XNprfi8TSp+RsSRxav6DBw2ou5viGjAjP2ddrO6Lw37XUYV0igS+BeDNEPA4dwI ZlbCzNE7qSXK2rjmGjyu7GCJ3+NOxJDQ8GdxkTDtpPrBF2kCOkQ= =NAId -----END PGP SIGNATURE----- Merge tag 'bcachefs-2024-04-15' of https://evilpiepirate.org/git/bcachefs Pull yet more bcachefs fixes from Kent Overstreet: "This gets recovery working again for the affected user I've been working with, and I'm still waiting to hear back on other bug reports but should fix it for everyone else who's been having issues with recovery. - Various recovery fixes: - fixes for the btree_insert_entry being resized on path allocation btree_path array recently became dynamically resizable, and btree_insert_entry along with it; this was being observed during journal replay, when write buffer btree updates don't use the write buffer and instead use the normal btree update path - multiple fixes for deadlock in recovery when we need to do lots of btree node merges; excessive merges were clocking up the whole pipeline - write buffer path now correctly does btree node merges when needed - fix failure to go RW when superblock indicates recovery passes needed (i.e. to complete an unfinished upgrade) - Various unsafety fixes - test case contributed by a user who had two drives out of a six drive array write out a whole bunch of garbage after power failure - New (tiny) on disk format feature: since it appears the btree node scan tool will be a more regular thing (crappy hardware, user error) - this adds a 64 bit per-device bitmap of regions that have ever had btree nodes. - A path->should_be_locked fix, from a larger patch series tightening up invariants and assertions around btree transaction and path locking state.
