Merge tag 'ceph-for-5.16-rc1' of git://github.com/ceph/ceph-client

Pull ceph updates from Ilya Dryomov:
 "One notable change here is that async creates and unlinks introduced
  in 5.7 are now enabled by default. This should greatly speed up things
  like rm, tar and rsync. To opt out, wsync mount option can be used.

  Other than that we have a pile of bug fixes all across the filesystem
  from Jeff, Xiubo and Kotresh and a metrics infrastructure rework from
  Luis"
