2023-10-22bcachefs: Don't use inode btree key cache in fsck codeKent Overstreet
We had a cache coherency bug with the btree key cache in the fsck code - this fixes fsck to be consistent about not using it. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Don't use bkey cache for inode update in fsckKent Overstreet
fsck doesn't know about the btree key cache, and non-cached iterators aren't cache coherent (yet?) Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: New varintsKent Overstreet
Previous varint implementation used by the inode code was not nearly as fast as it could have been; partly because it was attempting to encode integers up to 96 bits (for timestamps) but this meant that encoding and decoding the length required a table lookup. Instead, we'll just encode timestamps greater than 64 bits as two separate varints; this will make decoding/encoding of inodes significantly faster overall.

2023-10-22bcachefs: Inode create optimizationKent Overstreet
On workloads that do a lot of multithreaded creates all at once, lock contention on the inodes btree turns out to still be an issue. This patch adds a small buffer of inode numbers that are known to be free, so that we can avoid touching the btree on every create. Also, this changes inode creates to update via the btree key cache for the initial create.

2023-10-22bcachefs: Kill bchfs_extent_update()Kent Overstreet
The generic IO path now handles inode updates for i_size and i_sectors - this means we can drop a fair amount of code from fs-io.c. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
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: Rewrite journal_seq_blacklist machineryKent Overstreet
Now, we store blacklisted journal sequence numbers in the superblock, not the journal: this helps to greatly simplify the code, and more importantly it's now implemented in a way that doesn't require all btree nodes to be visited before starting the journal - instead, we unconditionally blacklist the next 4 journal sequence numbers after an unclean shutdown.

2023-10-22bcachefs: add bcachefs_effective xattrsKent Overstreet
Allows seeing xattrs that were inherited, not explicitly set 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>
