Catching these early makes them a lot easier to track down.

bcachefs: Kill JOURNAL_ERRORS()2025-03-24T13:50:35ZKent Overstreet2025-03-18T19:52:08Zurn:sha1:4a4000b9a6fd0d1de0349cd398433fd7fdf64292
Convert these to standard error codes, which means we can pass them
outside the journal code, they're easier to pass to tracepoints, etc.

Incorrectly handled transaction restarts can be a source of heisenbugs;
add a mode where we randomly inject them to shake them out.

bcachefs: "Journal stuck" timeout now takes into account device latency2025-01-21T23:32:05ZKent Overstreet2025-01-21T22:42:25Zurn:sha1:2c5d8a8347a8ea8c243245e2ed8d87dfbf9f54fb
If a block device (e.g. your typical consumer SSD) is taking multiple
seconds for IOs (typically flushes), we don't want to emit the "journal
stuck" message prematurely.
Also, make sure to drop the btree_trans srcu lock if we're blocking for
more than a second.

New helper for dropping all write locks; which is distinct from the
helper the transaction commit path uses, which is faster and only
touches updates.

bcachefs: Don't run overwrite triggers before insert2024-12-21T06:36:23ZKent Overstreet2024-12-12T07:27:52Zurn:sha1:92e31d425179c0f5b14d27ad1ad4a7b716c8db7e
This breaks when the trigger is inserting updates for the same btree, as
the inode trigger now does.

bcachefs: Plumb bkey_validate_context to journal_entry_validate2024-12-21T06:36:22ZKent Overstreet2024-12-08T02:36:15Zurn:sha1:60558d55f7e26c8aa2242718461642792fa200a4
This lets us print the exact location in the journal if it was found in
the journal, or correctly print if it was found in the superblock.

Add a new parameter to bkey validate functions, and use it to improve
invalid bkey error messages: we can now print the btree and depth it
came from, or if it came from the journal, or is a btree root.
