  ceph: move CEPH_SUPER_MAGIC definition to magic.h (2022-01-13 13:40:07 +0100)

There is a trivial conflict caused by removal of ceph_kvmalloc()
helper that went though the akpm tree.  I pushed the resolution to
for-linus-merged just in case.

----------------------------------------------------------------
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).
