Hi, this is an RFC to drop get_online_cpus from lru_add_drain_all ad this has caused a very subtle lockdep splats recently [1]. I didn't get even to properly test this yet and I am sending it early to check whether the thinking behind is sound. I am basically following the same pattern we have used for removing get_online_cpus from drain_all_pages which should be the similar case.
Does anybody see any obvious problem? [1] http://lkml.kernel.org/r/[email protected]
