It's not as critical as the GFP_THISNODE exemption, > which is why I didn't tag it for stable, but it's a bugfix as well. Changelog fail! : GFP_THISNODE is for callers that implement their own clever fallback to : remote nodes, and so no direct reclaim is invoked. There are many current : users that only want node exclusiveness but still want reclaim to make the : allocation happen. Convert them over to __GFP_THISNODE and update the : documentation to clarify GFP_THISNODE semantics. what bug does it fix and what are the user-visible effects?? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
