rhashtable: Add parent argument to mutex_is_held
Currently mutex_is_held can only test locks in the that are global since it takes no arguments. This prevents rhashtable from being used in places where locks are lock, e.g., per-namespace locks. This patch adds a parent field to mutex_is_held and rhashtable_params so that local locks can be used (and tested). Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.
