ceph: return -EINVAL if given fsc mount option on kernel w/o support (2019-11-07 18:03:23 +0100)

----------------------------------------------------------------
Some late-breaking dentry handling fixes from Al and Jeff, a patch to
further restrict copy_file_range() to avoid potential data corruption
from Luis and a fix for !CONFIG_CEPH_FSCACHE kernels. Everything but
the fscache fix is marked for stable.

----------------------------------------------------------------
Al Viro (2):
ceph: fix RCU case handling in ceph_d_revalidate()
ceph: add missing check in d_revalidate snapdir handling

Jeff Layton (2):
ceph: don't try to handle hashed dentries in non-O_CREAT atomic_open
ceph: return -EINVAL if given fsc mount option on kernel w/o support

Luis Henriques (2):
ceph: fix use-after-free in __ceph_remove_cap()
ceph: don't allow copy_file_range when stripe_count != 1
