Subject: [PATCH] mm/mempolicy.c: use in_task() in mempolicy_slab_node()
References: bsc#1190208 (MM functional and performance backports)
Patch-mainline: v5.15-rc1
Git-commit: 38b031dd4d03542d963eebe600d67ea34f47eb65
Obsoleted in_intrrupt() include task context with disabled BH, it's better
to use in_task() instead.
