  "message": "[PATCH] mm: page_state opt\n\nOptimise page_state manipulations by introducing interrupt unsafe accessors\nto page_state fields.  Callers must provide their own locking (either\ndisable interrupts or not update from interrupt context).\n\nSwitch over the hot callsites that can easily be moved under interrupts off\nsections.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
