Now update atime of file, only for client had CEPH_CAP_FLE_EXCL.But for atime, if one can read he can update this attribte.
For this feature,it need both client and mds modify.
PATCH1,it modify the mds to support.
PATCH2,it modify the client to suport.
PATCH3, it support this feature for sync_read mode.
Jianpeng Ma (3):
mds: update atime if client can read
ceph: update atime after read-operation.
ceph: For ceph_sync_read, update the atime of file.
