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)" * tag 'ceph-for-5.17-rc1' of git://github.com/ceph/ceph-client: ceph: move CEPH_SUPER_MAGIC definition to magic.h ceph: remove redundant Lsx caps check ceph: add new "nopagecache" option ceph: don't check for quotas on MDS stray dirs ceph: drop send metrics debug message rbd: make const pointer spaces a static const array ceph: Fix incorrect statfs report for small quota ceph: mount syntax module parameter doc: document new CephFS mount device syntax ceph: record updated mon_addr on remount ceph: new device mount syntax libceph: rename parse_fsid() to ceph_parse_fsid() and export libceph: generalize addr/ip parsing based on delimiter
