From 7b4ce2353467fdab6e003be7a3129fb09b09deac Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 13 Nov 2014 18:11:22 +0800 Subject: 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 Signed-off-by: David S.
