Merge tag 'ceph-for-5.17-rc3' of git://github.com/ceph/ceph-client
Pull ceph fixes from Ilya Dryomov:
"A patch to make it possible to disable zero copy path in the messenger
to avoid checksum or authentication tag mismatches and ensuing session
resets in case the destination buffer isn't guaranteed to be stable"
* tag 'ceph-for-5.17-rc3' of git://github.com/ceph/ceph-client:
libceph: optionally use bounce buffer on recv path in crc mode
libceph: make recv path in secure mode work the same as send path
