Subject[PATCH 4.19 118/142] cachefiles: Explicitly cast enumerated type in put_object
Date
4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit b7e768b7e3522695ed36dcb48ecdcd344bd30a9b ]

Clang warns when one enumerated type is implicitly converted to another.

fs/cachefiles/namei.c:247:50: warning: implicit conversion from
enumeration type 'enum cachefiles_obj_ref_trace' to different
enumeration type 'enum fscache_obj_ref_trace' [-Wenum-conversion]
cache->cache.ops->put_object(&xobject->fscache,
cachefiles_obj_put_wait_retry);

Silence this warning by explicitly casting to fscache_obj_ref_trace,
which is also done in put_object.
