It's certainly not _writes_ that are failing and "THP_WRITE_FAILED" makes it sound that way. Also, why do we need to differentiate these from the existing anon-hugepage vm stats? The alloc_pages() call seems to be doing the exact same thing in the end. Is one more likely to succeed than the other? -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
