  "message": "[PATCH] cpuset: memory_spread_slab drop useless PF_SPREAD_PAGE check\n\nThe hook in the slab cache allocation path to handle cpuset memory\nspreading for tasks in cpusets with \u0027memory_spread_slab\u0027 enabled has a\nmodest performance bug.  The hook calls into the memory spreading handler\nalternate_node_alloc() if either of \u0027memory_spread_slab\u0027 or\n\u0027memory_spread_page\u0027 is enabled, even though the handler does nothing\n(albeit harmlessly) for the page case\n\nFix - drop PF_SPREAD_PAGE from the set of flag bits that are used to\ntrigger a call to alternate_node_alloc().\n\nThe page case is handled by separate hooks -- see the calls conditioned on\ncpuset_do_page_mem_spread() in mm/filemap.c\n\nSigned-off-by: Paul Jackson \u003cpj@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
