This patch in linux-next breaks numa detection. numa_init() will zero
numa_meminfo. If acpi_numa_init() does not call early_parse_srat(), we will
have no memory numa info.

Now discard merge works, add plug for blkdev_issue_discard. This will help
discard request merge especially for raid0 case. In raid0, a big discard
request is split to small requests, and if correct plug is added, such small
requests can be merged in low layer.

e the two cfqq are different, but didn't cause kernel

Neil,
This is another attempt to make raid5 stripe handling multi-threading.
Recent workqueue improvement for unbound workqueue looks very promising to the
raid5 usage. I had details in the first patch.
The patches are against your tree with patch 'raid5: make release_stripe
lockless' and 'raid5:
ase request size dispatching down to low level layer. The impact depends
on thread number, raid configuration and workload. So multi-thread raid5 might
not be proper for all setups.
Changes V1 -> V2:
1. remove WQ_NON_REENTRANT
2. disabling multi-threading by default
3. Add more descripti

In MD raid case, discard granularity might not be power of 2, for example, a
4-disk raid5 has 3*chunk_size discard granularity. Correct the calculation for
such cases.
