Merge tag 'ceph-for-6.16-rc1' of https://github.com/ceph/ceph-client

Pull ceph updates from Ilya Dryomov:

 - a one-liner that leads to a startling (but also very much rational)
   performance improvement in cases where an IMA policy with rules that
   are based on fsmagic matching is enforced

 - an encryption-related fixup that addresses generic/397 and other
   fstest failures

 - a couple of cleanups in CephFS
