  "message": "[PATCH] memory page alloc minor cleanups\n\n- s/freeliest/freelist/ spelling fix\n\n- Check for NULL *z zone seems useless - even if it could happen, so\n  what?  Perhaps we should have a check later on if we are faced with an\n  allocation request that is not allowed to fail - shouldn\u0027t that be a\n  serious kernel error, passing an empty zonelist with a mandate to not\n  fail?\n\n- Initializing \u0027z\u0027 to zonelist-\u003ezones can wait until after the first\n  get_page_from_freelist() fails; we only use \u0027z\u0027 in the wakeup_kswapd()\n  loop, so let\u0027s initialize \u0027z\u0027 there, in a \u0027for\u0027 loop.  Seems clearer.\n\n- Remove superfluous braces around a break\n\n- Fix a couple errant spaces\n\n- Adjust indentation on the cpuset_zone_allowed() check, to match the\n  lines just before it -- seems easier to read in this case.\n\n- Add another set of braces to the zone_watermark_ok logic\n\nFrom: Paul Jackson \u003cpj@sgi.com\u003e\n\n  Backout one item from a previous \"memory page_alloc minor cleanups\" patch.\n   Until and unless we are certain that no one can ever pass an empty zonelist\n  to __alloc_pages(), this check for an empty zonelist (or some BUG\n  equivalent) is essential.  The code in get_page_from_freelist() blow ups if\n  passed an empty zonelist.\n\nSigned-off-by: Paul Jackson \u003cpj@sgi.com\u003e\nAcked-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\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",
