From cdb4cba5a3c9fa27240d04f4f8dad316b10d995b Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 2 Sep 2014 14:46:01 -0400 Subject: [PATCH] percpu: remove @may_alloc from pcpu_get_pages() pcpu_get_pages() creates the temp pages array if not already allocated and returns the pointer to it. As the function is called from both [de]population paths and depopulation can only happen after at least one successful population, the param doesn't make any difference - the allocation will always happen on the population path anyway. Remove @may_alloc from pcpu_get_pages(). Also, add an lockdep assertion pcpu_alloc_mutex instead of vaguely stating that the exclusion is the caller's responsibility.
