Pull libata ZAC support from Tejun Heo: "This contains Zone ATA Command support for Shingled Magnetic Recording devices. In addition to sending the new commands down to the device, as ZAC commands depend on getting a lot of responses from the device, piping up responses is beefed up too. However, it doesn't involve changes to libata core mechanism or its interaction with upper layers, so I'm not expecting too many fallouts.

mm, compaction: distinguish between full and partial COMPACT_COMPLETE

2016-05-21T00:58:30Z

COMPACT_COMPLETE now means that compaction and free scanner met. This is not very useful information if somebody just wants to use this feedback and make any decisions based on that. The current caller might be a poor guy who just happened to scan tiny portion of the zone and that could be the reason no suitable pages were compacted. Make sure we distinguish the full and partial zone walks. Consumers should treat COMPACT_PARTIAL_SKIPPED as a potential success and be optimistic in retrying. The existing users of COMPACT_COMPLETE are conservatively changed to use COMPACT_PARTIAL_SKIPPED as well but some of them should be probably reconsidered and only defer the compaction only for COMPACT_COMPLETE with the new semantic. This patch shouldn't introduce any functional changes.

mm, compaction: distinguish COMPACT_DEFERRED from COMPACT_SKIPPED

2016-05-21T00:58:30Z

try_to_compact_pages() can currently return COMPACT_SKIPPED even when the compaction is defered for some zone just because zone DMA is skipped in 99% of cases due to watermark checks. This makes COMPACT_DEFERRED basically unusable for the page allocator as a feedback mechanism. Make sure we distinguish those two states properly and switch their ordering in the enum. This would mean that the COMPACT_SKIPPED will be returned only when all eligible zones are skipped. As a result COMPACT_DEFERRED handling for THP in __alloc_pages_slowpath will be more precise and we would bail out rather than reclaim.
