Subject: [PATCH] fs/dcache: init in_lookup_hashtable
|
|
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.9/older/patches-4.9.9-rt6.tar.xz
|
|
|
|
in_lookup_hashtable was introduced in commit 94bdd655caba ("parallel
|
|
lookups machinery, part 3") and never initialized but since it is in
|
|
the data it is all zeros. But we need this for -RT.
