[GIT PULL] Btrfs fixes for 6.15-rc4

[David Sterba <dsterba@suse.com>]

Hi,

please pull the following short fixes. Most of them are one-liners,
there's one preparatory patch in block layer moving some code around
and adding a helper that's used in a fix. Thanks.

- subpage mode fixes
  - access correct object (folio) when looking up bit offset
  - fix assertion condition for number of blocks per folio
  - fix upper boundary of locking range in hole punch

- zoned fixes
  - fix potential deadlock caught by lockdep when zone reporting and
    device freeze run in parallel
  - fix zone write pointer mismatch and NULL pointer dereference when
    metadata are converted from DUP to RAID1

- fix error handling when reloc inode creation fails

- in tree-checker, unify error code for header level check

- block layer: add helpers to read zone capacity

----------------------------------------------------------------
