Subject: ceph: silence sparse endianness warning in encode_caps_cb
Git-commit: ec1dff25b0a012711e10290039fbc8e1c5dd69fb
Patch-mainline: v4.15-rc1
References: FATE#324714
sparse warns:
fs/ceph/mds_client.c:2887:34: warning: incorrect type in assignment (different base types)
fs/ceph/mds_client.c:2887:34: expected restricted __le32 [assigned] [usertype] flock_len
fs/ceph/mds_client.c:2887:34: got int
At this point, it's just being used as a flag. It gets
overwritten later if the rest of the encoding succeeds.
