linux.git/fs/bcachefs/alloc_background.c, branch v6.17 Linux kernel source tree bcachefs: Don't log fsck err in the journal if doing repair elsewhere 2025-06-19T17:08:07+00:00 Kent Overstreet kent.overstreet@linux.dev 2025-06-19T16:50:06+00:00 32a01cd4334175a0ae42b3c3d7f37fd26468ecc3 This fixes exceeding the bump allocator limit when the allocator finds many buckets that need repair - they're repaired asynchronously, which means that every error logged a message in the bump allocator, without committing.
