Merge branch 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull nvdimm fixes from Dan Williams:
"A small crop of lockdep, sleeping while atomic, and other fixes /
band-aids in advance of the full-blown reworks targeting the next
merge window. The largest change here is "libnvdimm: fix blk free
space accounting" which deletes a pile of buggy code that better
testing would have caught before merging. The next change that is
borderline too big for a late rc is switching the device-dax locking
from rcu to srcu, I couldn't think of a smaller way to make that fix.
The __copy_user_nocache fix will have a full replacement in 4.12 to
move those pmem special case considerations into the pmem driver. The
"libnvdimm: band aid btt vs clear poison locking" commit admits that
our error clearing support for btt went in broken, so we just disable
it in 4.11 and -stable. A replacement / full fix is in the pipeline
for 4.12
Some of these would have been caught earlier had DEBUG_ATOMIC_SLEEP
been enabled on my development station. I wonder if we should have:
config DEBUG_ATOMIC_SLEEP
default PROVE_LOCKING
...since I mistakenly thought I got both with PROVE_LOCKING=y.
These have received a build success notification from the 0day robot,
and some have appeared in a -next release with no reported issues"
