Merge tag 'erofs-for-5.17-rc3-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs

Pull erofs fixes from Gao Xiang:
 "Two fixes related to fsdax cleanup in this cycle and ztailpacking to
  fix small compressed data inlining. There is also a trivial cleanup to
  rearrange code for better reading.

  Summary:

   - fix fsdax partition offset misbehavior

   - clean up z_erofs_decompressqueue_work() declaration

   - fix up EOF lcluster inlining, especially for small compressed data"

* tag 'erofs-for-5.17-rc3-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs:
  erofs: fix small compressed files inlining
  erofs: avoid unnecessary z_erofs_decompressqueue_work() declaration
  erofs: fix fsdax partition offset handling
