kernel/fs/bcachefs/alloc_background.h, 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.

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.

Specialize the .to_text() for alloc_v4, to avoid the temporary on the
stack for conversion from old versions.

Add a helper that lets us change bch_member.data_allowed at runtime.

All the fastpaths that need device usage don't need the sector totals or
fragmentation, just bucket counts.
Split bch_dev_usage up into two different versions, the normal one with
just bucket counts.
This is also a stack usage improvement, since we have a bch_dev_usage on
the stack in the allocation path.

bcachefs: Don't recurse in check_discard_freespace_key2024-12-21T06:36:21ZKent Overstreetkent.overstreet@linux.dev2024-11-29T00:30:23Zurn:sha1:2cd85fea49d850629404d4668e104466114598e3
When calling check_discard_freeespace_key from the allocator, we can't
repair without recursing - run it asynchronously instead.

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.

check_discard_freespace_key() was doing all the same checks as
try_alloc_bucket(), but with repair.

bcachefs: fix shift oob in alloc_lru_idx_fragmentation2024-10-24T21:41:43ZJeongjun Parkaha310510@gmail.com2024-10-21T15:43:56Zurn:sha1:5c41f75d1b921b9eaf79588cdd3b22b00fb4ec52
The size of a.data_type is set abnormally large, causing shift-out-of-bounds.
To fix this, we need to add validation on a.data_type in
alloc_lru_idx_fragmentation().
