Merge tag 'ceph-for-5.17-rc1' of git://github.com/ceph/ceph-client

Pull ceph updates from Ilya Dryomov:
 "The highlight is the new mount "device" string syntax implemented by
  Venky Shankar. It solves some long-standing issues with using
  different auth entities and/or mounting different CephFS filesystems
  from the same cluster, remounting and also misleading /proc/mounts
  contents. The existing syntax of course remains to be maintained.

  On top of that, there is a couple of fixes for edge cases in quota and
  a new mount option for turning on unbuffered I/O mode globally instead
  of on a per-file basis with ioctl(CEPH_IOC_SYNCIO)"
