Hi Jens,
these small blk-mq core updates fell out of the scsi multiqueue work.

Please read the FAQ at
__blk_put_request needs to call into the blk-mq code just like
blk_put_request. As we don't have the queue lock in this case both
end up calling the same function.

There is plenty of anecdotal evidence and a load of blog posts
suggesting that using "drop_caches" periodically keeps your system
running in "tip top shape". Perhaps adding some kernel documentation
will increase the amount of accurate data on its use.

The broadcast timer registration has to be done only when
GENERIC_CLOCKEVENTS_BROADCAST and TICK_ONESHOT config options are enabled.
Also fix max_delta_ticks value for the pseudo clock device.

In case the compiler does not support the stack-protector option,
unset the flag to avoid build failures. Printing a warning is enough
to let the user know that this flag will not be used.

Instead of returning NULL from try_get_mem_cgroup_from_mm() when the
mm owner is exiting, just return root_mem_cgroup. This makes sense
for all callsites and gets rid of some of them having to fallback
manually.

It used to disable preemption and run sanity checks but now it's only
taking a number out of one percpu counter and putting it into another.

__mem_cgroup_try_charge duplicates get_mem_cgroup_from_mm for charges

Some callsites pass a memcg directly, some callsites pass a mm that
first has to be translated to an mm. This makes for a terrible
function interface.
Just push the mm-to-memcg translation into the respective callsites

Reparenting memory charges in the css_free() callback was meant as a

Hi,
This series adds a generic cacheinfo support similar to topology. The
implementation is based on x86 cacheinfo support. Currently x86, powerpc,
ia64 and s390 have their own implementations. While adding similar support
to ARM and ARM64, here is the attempt to make it
Ticket locks for ppc, version 2. Changes since v1:
* The atomically exchanged entity is always 32 bits.
* asm inline string variations thus removed.
* Carry the additional holder hint only #if defined(CONFIG_PPC_SPLPAR)

There's actually very little difference between vfs_rename_dir() and
vfs_rename_other() so move both inline into vfs_rename() which still stays
reasonably readable.

Add d_is_dir(dentry) helper which is analogous to S_ISDIR().

Changes since the last version (based on Al's review):
- cross-rename: fix locking of nondirectories for NFSv4
- ext4: split cross-rename and plain rename into separate functions
- introduce i_op->rename2 with flags, don't touch ->rename
- last (optional) patch to merge ->rename2 back into
From: Miklos Szeredi
Add new renameat2 syscall, which is the same as renameat with an added
flags argument.
Pass flags to vfs_rename() and to i_op->rename() as well.

Move the d_move() in vfs_rename_dir() up, similarly to how it's done in
vfs_rename_other(). The next patch will consolidate these two functions
and this is the only structural difference between them.
I'm not sure if doing the d_move() after the dput is even valid. But

If this flag is specified and the target of the rename exists then the
rename syscall fails with EEXIST.
The VFS does the existence checking, so it is trivial to enable for most
local filesystems. This patch only enables it in ext4.

Move checking i_nlink from after ext4_get_first_dir_block() to before. The
check doesn't rely on the result of that function and the function only
fails on fs corruption, so the order shouldn't matter.

Cross rename (exchange source and dest) will need to call some of these
helpers for both source and dest, while overwriting rename currently only
calls them for one or the other. This also makes the code easier to
