If page migration fails due to -ENOMEM, nr_failed should still be incremented for proper statistics. This was encountered recently when all page migration vmstats showed 0, and inferred that migrate_pages() was never called, although in reality the first page migration failed because compaction_alloc() failed to find a migration target. This patch increments nr_failed so the vmstat is properly accounted on ENOMEM.
