bcachefs: New on disk format: Backpointers This patch adds backpointers: we now have a reverse index from device and offset on that device (specifically, offset within a bucket) back to btree nodes and (non cached) data extents. The first 40 backpointers within a bucket are stored in the alloc key; after that backpointers spill over to the next backpointers btree. This is to help avoid performance regressions from additional btree updates on large streaming workloads. This patch adds all the code for creating, checking and repairing backpointers. The next patch in the series is going to use backpointers for copygc - finally getting rid of the need to scan all extents to do copygc. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

bcachefs: btree_journal_iter.c Split out a new file from recovery.c for managing the list of keys we read from the journal: before journal replay finishes the btree iterator code needs to be able to iterate over and return keys from the journal as well, so there's a fair bit of code here.

btree_journal_iter.o \
bcachefs: Btree key cache This introduces a new kind of btree iterator, cached iterators, which point to keys cached in a hash table. The cache also acts as a write cache - in the update path, we journal the update but defer updating the btree until the cached entry is flushed by journal reclaim. Cache coherency is for now up to the users to handle, which isn't ideal but should be good enough for now. These new iterators will be used for updating inodes and alloc info (the alloc and stripes btrees).

btree_update_interior.o \
bcachefs: Btree write buffer This adds a new method of doing btree updates - a straight write buffer, implemented as a flat fixed size array. This is only useful when we don't need to read from the btree in order to do the update, and when reading is infrequent - perfect for the LRU btree. This will make LRU btree updates fast enough that we'll be able to use it for persistently indexing buckets by fragmentation, which will be a massive boost to copygc performance. Changes: - A new btree_insert_type enum, for btree_insert_entries. Specifies btree, btree key cache, or btree write buffer. - bch2_trans_update_buffered(): updates via the btree write buffer don't need a btree path, so we need a new update path. - Transaction commit path changes: The update to the btree write buffer both mutates global, and can fail if there isn't currently room. Therefore we do all write buffer updates in the transaction all at once, and also if it fails we have to revert filesystem usage counter changes. If there isn't room we flush the write buffer in the transaction commit error path and retry. - A new persistent option, for specifying the number of entries in the write buffer.

bcachefs: Improved errcodes Instead of overloading standard error codes (EINTR/EAGAIN), and defining short lists of error codes in multiple places that potentially end up overlapping & conflicting, we're now going to have one master list of error codes. Error codes are defined with an x-macro: thus we also have bch2_err_str() now. Also, error codes have a class field. Now, instead of checking for errors with ==, code should use bch2_err_matches(), which returns true if the error is equal to or a sub-error of the error class. This means we can define unique errors for every source location where an error is generated, which will help improve our error messages. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

bcachefs: Nocow support This adds support for nocow mode, where we do writes in-place when possible. Patch components: - New boolean filesystem and inode option, nocow: note that when nocow is enabled, data checksumming and compression are implicitly disabled - To prevent in-place writes from racing with data moves (data_update.c) or bucket reuse (i.e. a bucket being reused and re-allocated while a nocow write is in flight, we have a new locking mechanism. Buckets can be locked for either data update or data move, using a fixed size hash table of two_state_shared locks. We don't have any chaining, meaning updates and moves to different buckets that hash to the same lock will wait unnecessarily - we'll want to watch for this becoming an issue. - The allocator path also needs to check for in-place writes in flight to a given bucket before giving it out: thus we add another counter to bucket_alloc_state so we can track this. - Fsync now may need to issue cache flushes to block devices instead of flushing the journal. We add a device bitmask to bch_inode_info, ei_devs_need_flush, which tracks devices that need to have flushes issued - note that this will lead to unnecessary flushes when other codepaths have already issued flushes, we may want to replace this with a sequence number. - New nocow write path: look up extents, and if they're writable write to them - otherwise fall back to the normal COW write path. XXX: switch to sequence numbers instead of bitmask for devs needing journal flush XXX: ei_quota_lock being a mutex means bch2_nocow_write_done() needs to run in process context - see if we can improve this Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

The upcoming disk accounting rewrite is not going to be fully compatible: we're going to have to regenerate accounting both when upgrading to the new version, and also from downgrading from the new version, since the new method of doing disk space accounting is a completely different architecture based on deltas, and synchronizing them for every jounal entry write to maintain compatibility is going to be too expensive and impractical.
