Merge tag 'erofs-for-5.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs

Pull erofs updates from Gao Xiang:
 "The most interesting part is the new mount api conversion, which is
  actually a old patch already pending for several cycles. And the
  others are recent trivial cleanups here.

  Summary:

   - Convert to use the new mount apis

   - Some random cleanup patches"

* tag 'erofs-for-5.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs:
  erofs: suppress false positive last_block warning
  erofs: convert to use the new mount fs_context api
  erofs: code cleanup by removing ifdef macro surrounding
