| H A D | compaction.h | diff cf378319d335663b6722e74db0211b8af55049d5 Fri Oct 07 18:57:41 CDT 2016 Vlastimil Babka <vbabka@suse.cz> mm, compaction: rename COMPACT_PARTIAL to COMPACT_SUCCESS
COMPACT_PARTIAL has historically meant that compaction returned after
doing some work without fully compacting a zone. It however didn't
distinguish if compaction terminated because it succeeded in creating
the requested high-order page. This has changed recently and now we
only return COMPACT_PARTIAL when compaction thinks it succeeded, or the
high-order watermark check in compaction_suitable() passes and no
compaction needs to be done.
So at this point we can make the return value clearer by renaming it to
COMPACT_SUCCESS. The next patch will remove some redundant tests for
success where compaction just returned COMPACT_SUCCESS.
