kernel/fs/bcachefs/backpointers.c, branch linux-rolling-stableHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-rolling-stable2025-09-29T20:43:52ZRemove bcachefs core code2025-09-29T20:43:52ZLinus Torvaldstorvalds@linux-foundation.org2025-09-29T20:43:52Zurn:sha1:f2c61db29f277b9c80de92102fc532cc247495cd
bcachefs was marked 'externally maintained' in 6.17 but the code
remained to make the transition smoother.
It's now a DKMS module, making the in-kernel code stale, so remove
it to avoid any version confusion.

Add a tracepoint for any time we return an error and unwind.

bcachefs: Replace rcu_read_lock() with guards2025-06-01T04:03:12ZKent Overstreetkent.overstreet@linux.dev2025-05-24T20:33:39Zurn:sha1:18dad454cd16cbb4c219dbd19a0008af52eb294a
The new guard(), scoped_guard() allow for more natural code.
Some of the uses with creative flow control have been left.

bcachefs: bch2_check_bucket_backpointer_mismatch()2025-05-22T00:15:04ZKent Overstreetkent.overstreet@linux.dev2025-05-09T21:01:05Zurn:sha1:39cea302f13a0a9dc4cf39248529a42e79d06842
Detect buckets with missing backpointers, and run repair on demand.
__bch2_move_data_phys() now calls
bch2_check_bucket_backpointer_mismatch() as it walks buckets, which
checks for missing backpointers by comparing backpointers against bucket
sector counts.
When missing backpointers are detected, we kick off
bch2_check_extents_to_backpointers() asynchronously - right away if
we're trying to evacuate, or with a threshold if we're just running
copygc.

Add some more helpers, and mismatches is now a superset of the empty
bitmap - simplifies most checks.

bcachefs: Reduce usage of recovery.curr_pass2025-05-22T00:15:03ZKent Overstreetkent.overstreet@linux.dev2025-05-13T21:36:55Zurn:sha1:7ed4c14e20be2b113e111ec9fa1803c778e00280
We want recovery.curr_pass to be private to the recovery passes code,
for better showing recovery pass status; also, it may rewind and is
generally not the correct member to use.

bch_fs has gotten obnoxiously big, let's start organizing thins a bit
better.

We'd like users to be able to debug without building custom kernels, so
this will help us get rid of CONFIG_BCACHEFS_DEBUG, at least for most
things.
