2023-10-22bcachefs: Use cached iterators for inode updatesKent Overstreet
This switches inode updates to use cached btree iterators - which should be a nice performance boost, since lock contention on the inodes btree can be a bottleneck on multithreaded workloads.

2023-10-22bcachefs: Kill bkey_type_successorKent Overstreet
Previously, BTREE_ID_INODES was special - inodes were indexed by the inode field, which meant the offset field of struct bpos wasn't used, which led to special cases in e.g. the btree iterator code. Now, inodes in the inodes btree are indexed by the offset field. Also: prevously min_key was special for extents btrees, min_key for extents would equal max_key for the previous node. Now, min_key = bkey_successor() of the previous node, same as non extent btrees. This means we can completely get rid of btree_type_sucessor/predecessor. Also make some improvements to the metadata IO validate/compat code. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Make sure we're releasing btree iteratorsKent Overstreet
This wasn't originally required, but this is the model we're moving towards. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Split out btree_trigger_flagsKent Overstreet
The trigger flags really belong with individual btree_insert_entries, not the transaction commit flags - this splits out those flags and unifies them with the BCH_BUCKET_MARK flags. Todo - split out btree_trigger.c from buckets.c Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2023-10-22bcachefs: Convert all bch2_trans_commit() users to BTREE_INSERT_ATOMICKent Overstreet
BTREE_INSERT_ATOMIC should really be the default mode, and there's not that much code that doesn't need it - so this is prep work for getting rid of the flag. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Initialize padding space after alloc bkeyJustin Husted
Packed bkeys are padded up to 64 bit alignment, but the alloc bkey type was not clearing the pad bytes after the last data byte. This left the key possibly containing some random garbage at the end. This problem was found using valgrind. This patch also changes a path with the inode bkey to clear in the same way.

2023-10-22bcachefs: Factor out fs-common.cKent Overstreet
This refactoring makes the code easier to understand by separating the bcachefs btree transactional code from the linux VFS code - but more importantly, it's also to share code with the fuse port. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Don't use sha256 for siphash str hash keyKent Overstreet
With the refactoring that's coming to add fuse support, we want bch2_hash_info_init() to be cheaper so we don't have to rely on anything cached besides the inode in the btree. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2023-10-22bcachefs: Make bkey types globally uniqueKent Overstreet
this lets us get rid of a lot of extra switch statements - in a lot of places we dispatch on the btree node type, and then the key type, so this is a nice cleanup across a lot of code. Also improve the on disk format versioning stuff. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
