2017-02-23scsi: qedf: fixup compilation warning about atomic_t usageDupuis, Chad
Based on an original patch by Hannes Reinecke. The driver didn't follow the atomic_t vs refcount_t change, and anyway one should be using kref_read() instead of accessing the counter inside an kref.

2017-02-23PM / Domains: Power off masters immediately in the power off sequenceUlf Hansson
Once a subdomain is powered off, genpd queues a power off work for each of the subdomain's corresponding masters, thus postponing the masters to be powered off to a later point. When genpd used intermediate power off states, which was removed in commit ba2bbfbf6307 ("PM / Domains: Remove intermediate states from the power off sequence"), this behaviour made sense, but now it simply doesn't. Genpd can easily try to power off the masters in the same context as the subdomain, of course by acquiring/releasing the lock. Then, let's convert to this behaviour, as it avoids unnecessary works from being queued. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Rafael J.

There are two issues, introduced by commit 8e58e32(md/raid1: use bio_clone_bioset_partial() in case of write behind): - bio_clone_bioset_partial() uses bytes instead of sectors as parameters - in writebehind mode, we return bio if all !writemostly disk bios finish, which could happen before writemostly disk bios run.

2017-02-23f2fs: add ovp valid_blocks check for bg gc victim to fg_gcHou Pengyang
For foreground gc, greedy algorithm should be adapted, which makes this formula work well: (2 * (100 / config.overprovision + 1) + 6) But currently, we fg_gc have a prior to select bg_gc victim segments to gc first, these victims are selected by cost-benefit algorithm, we can't guarantee such segments have the small valid blocks, which may destroy the f2fs rule, on the worstest case, would consume all the free segments. This patch fix this by add a filter in check_bg_victims, if segment's has # of valid blocks over overprovision ratio, skip such segments.

2017-02-23blk-mq-sched: separate mark hctx and queue restart operationsOmar Sandoval
In blk_mq_sched_dispatch_requests(), we call blk_mq_sched_mark_restart() after we dispatch requests left over on our hardware queue dispatch list. This is so we'll go back and dispatch requests from the scheduler. In this case, it's only necessary to restart the hardware queue that we are running; there's no reason to run other hardware queues just because we are using shared tags. So, split out blk_mq_sched_mark_restart() into two operations, one for just the hardware queue and one for the whole request queue. The core code only needs the hctx variant, but I/O schedulers will want to use both. This also requires adjusting blk_mq_sched_restart_queues() to always check the queue restart flag, not just when using shared tags.

2017-02-23blk-mq: use sbq wait queues instead of restart for driver tagsOmar Sandoval
Commit 50e1dab86aa2 ("blk-mq-sched: fix starvation for multiple hardware queues and shared tags") fixed one starvation issue for shared tags. However, we can still get into a situation where we fail to allocate a tag because all tags are allocated but we don't have any pending requests on any hardware queue. One solution for this would be to restart all queues that share a tag map, but that really sucks. Ideally, we could just block and wait for a tag, but that isn't always possible from blk_mq_dispatch_rq_list(). However, we can still use the struct sbitmap_queue wait queues with a custom callback instead of blocking. This has a few benefits: 1. It avoids iterating over all hardware queues when completing an I/O, which the current restart code has to do. 2. It benefits from the existing rolling wakeup code. 3. It avoids punting to another thread just to have it block. Signed-off-by: Omar Sandoval <osandov@fb.com> Signed-off-by: Jens Axboe <axboe@fb.com>

A device may change capabilities after each reset, e.g. due to a firmware upgrade. We should thus check for Security Send/Receive and OPAL support after each reset. Based on patches from Christoph and Keith. Signed-off-by: Scott Bauer <scott.bauer@intel.com> Signed-off-by: Jens Axboe <axboe@fb.com>

2017-02-23f2fs: enable inline_xattr by defaultChao Yu
In android, since SElinux is enable, security policy will be appliedd for each file, it stores in inode as an xattr entry, so it will take one 4k size node block additionally for each file. Let's enable inline_xattr by default in order to save storage space. Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

2017-02-23f2fs: change recovery policy of xattr node blockChao Yu
Currently, if we call fsync after updating the xattr date belongs to the file, f2fs needs to trigger checkpoint to keep xattr data consistent. But, this policy cause low performance as checkpoint will block most foreground operations and cause unneeded and unrelated IOs around checkpoint. This patch will reuse regular file recovery policy for xattr node block, so, we change to write xattr node block tagged with fsync flag to warm area instead of cold area, and during recovery, we search warm node chain for fsynced xattr block, and do the recovery. So, for below application IO pattern, performance can be improved obviously: - touch file - create/update/delete xattr entry in file - fsync file Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

Declare fscrypt_operations structure as const as it is only stored in the s_cop field of a super_block structure. This field is of type const, so fscrypt_operations structure having this property can be made const too.

2017-02-23f2fs: avoid out-of-order execution of atomic writesJaegeuk Kim
We need to flush data writes before flushing last node block writes by using FUA with PREFLUSH. We don't need to guarantee precedent node writes since if those are not written, we can't reach to the last node block when scanning node block chain during roll-forward recovery. Afterwards f2fs_wait_on_page_writeback guarantees all the IO submission to disk, which builds a valid node block chain.
