e6477000fc staging:iio:dummy Add event support + fake event generator
The event generator is not very pretty but does the job and
allows this driver to look a lot more like a normal driver
than it otherwise would.

3a84331db2 staging:iio:Documentation Simple dummy driver to explain the basics
The documenation explaining how to go about writing a driver is lagging
horribly, so here is another approach; an actual driver with
lots of explanatory comments.

Note it is currently minimal in that there are no events and no
buffer.  With care they can probably be added in additional files
without messing up the clarity of what we have here.

V2: Addressed some of Manuel Stahl's feedback.

Fixed up kernel doc.
Added more general description.

d2fffd6c2f staging:iio: fix removal path to allow correct freeing.
Fix a dumb lack of consideration of the effect of combining
the iio_device_unregister and iio_free_device calls into
one.  There is no valid place to free some of the sysfs

00bf256011 staging: zcache: remove zcache_direct_reclaim_lock
zcache_do_preload() currently does a spin_trylock() on the
zcache_direct_reclaim_lock. Holding this lock intends to prevent
shrink_zcache_memory() from evicting zbud pages as a result
of a preload.

However, it also prevents two threads from
executing zcache_do_preload() at the same time.  The first
thread will obtain the lock and the second thread's spin_trylock()
will fail (an aborted preload) causing the page to be either lost
(cleancache) or pushed out to the swap device (frontswap). It
also doesn't ensure that the call to shrink_zcache_memory() is
on the same thread as the call to zcache_do_preload().

Additional, there is no need for this mechanism because all
zcache_do_preload() calls that come down from cleancache already
have PF_MEMALLOC set in the process flags which prevents
direct reclaim in the memory manager. If the zcache_do_preload()
call is done from the frontswap path, we _want_ reclaim to be
done (which it isn't right now).

This patch removes the zcache_direct_reclaim_lock and related
statistics in zcache.

Based on v3.1-rc8

3d65c85f91 staging: zcache: reduce tmem bucket lock contention
tmem uses hash buckets each with their own rbtree and lock to
quickly lookup tmem objects.  tmem has TMEM_HASH_BUCKETS (256)
buckets per pool.  However, because of the way the tmem_oid is
generated for frontswap pages, only 16 unique tmem_oids are being
generated, resulting in only 16 of the 256 buckets being used.
This cause high lock contention for the per bucket locks.

This patch changes SWIZ_BITS to include more bits of the offset.
The result is that all 256 hash buckets are potentially used resulting in a
95% drop in hash bucket lock contention.
