Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/shli/md

Pull MD updates from Shaohua Li:

- Add Partial Parity Log (ppl) feature found in Intel IMSM raid array
by Artur Paszkiewicz. This feature is another way to close RAID5
writehole. The Linux implementation is also available for normal
RAID5 array if specific superblock bit is set.

- A number of md-cluser fixes and enabling md-cluster array resize from
Guoqing Jiang

- A bunch of patches from Ming Lei and Neil Brown to rewrite MD bio
handling related code. Now MD doesn't directly access bio bvec,
bi_phys_segments and uses modern bio API for bio split.

- Improve RAID5 IO pattern to improve performance for hard disk based
RAID5/6 from me.

- Several patches from Song Liu to speed up raid5-cache recovery and
allow raid5 cache feature disabling in runtime.

- Fix a performance regression in raid1 resync from Xiao Ni.

- Other cleanup and fixes from various people.

md/raid10: simplify the splitting of requests.

raid10 splits requests in two different ways for two different
reasons.

First, bio_split() is used to ensure the bio fits with a chunk.
Second, multiple r10bio structures are allocated to represent the
different sections that need to go to different devices, to avoid
known bad blocks.

This can be simplified to just use bio_split() once, and not to use
multiple r10bios.
We delay the split until we know a maximum bio size that can
be handled with a single r10bio, and then split the bio and queue
the remainder for later handling.

As with raid1, we allocate a new bio_set to help with the splitting.
It is not correct to use fs_bio_set in a device driver.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/shli/md

Pull MD updates from Shaohua Li:

- a raid5 writeback cache feature.

The goal is to aggregate writes to make full stripe write and reduce
read-modify-write. It's helpful for workload which does sequential
write and follows fsync for example. This feature is experimental and
off by default right now.

- FAILFAST support.

This fails IOs to broken raid disks quickly, so can improve latency.
It's mainly for DASD storage, but some patches help normal raid array
too.

- support bad block for raid array with external metadata

- AVX2 instruction support for raid6 parity calculation

- normalize MD info output

- add missing blktrace

- other bug fixes

md/raid10: add failfast handling for reads.

If a device is marked FailFast, and it is not the only
device we can read from, we mark the bio as MD_FAILFAST.

If this does fail-fast, we don't try read repair but just
allow failure.

If it was the last device, it doesn't get marked Faulty so
the retry happens on the same device - this time without
FAILFAST. A subsequent failure will not retry but will just
pass up the error.

During resync we may use FAILFAST requests, and on a failure
we will simply use the other device(s).

During recovery we will only use FAILFAST in the unusual
case were there are multiple places to read from - i.e. if
there are > 2 devices. If we get a failure we will fail the
device and complete the resync/recovery with remaining
devices.
