Subject: [PATCH 091/233] bcachefs: Delete backpointers check in
try_alloc_bucket()
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: 8bit
try_alloc_bucket() has a "safety" check, which avoids allocating a
bucket if there's any backpointers present.
But backpointers are not the source of truth for live data in a bucket,
the bucket sector counts are; this check was fairly useless, and we're
also deferring backpointers checks from fsck to runtime in the near
future.
