| |
The nr_dirty_[background_]threshold fields are misplaced before the numa_* fields, and users will read strange values.
This is the right order. Before patch, nr_dirty_background_threshold will read as 0 (the value from numa_miss).
numa_hit 128501 numa_miss 0 numa_foreign 0 numa_interleave 7388 numa_local 128501 numa_other 0 nr_dirty_threshold 144291 nr_dirty_background_threshold 72145
