ceph: check inode caps in ceph_d_revalidate
Some inodes in readdir reply may have no caps. Getattr mds request for these inodes can return -ESTALE. The fix is consider dentry that links to inode with no caps as invalid. Invalid dentry causes a lookup request to send to the mds, the MDS will send caps back. Signed-off-by: Yan, Zheng <zheng.z.yan@intel.com>
