Hello Maintainers:
When build h8300h with defconfig, an 'built-in' issue occurs. I can add

it is correct, but it seems not 'standard'.
So welcome any additional suggestions or completions, thanks.

For platform h8300h and h8s, user_disable_single_step() is already

It does not make sense to show ti prefix in pinconf_generic_dt_subnode_to_map()
dev_err messages.

A race condition may happen if two threads are both trying to open the same sg
with O_EXCL simultaneously. It's possible that they both find fsds list is
empty and get_exclude(sdp) returns 0, then they both call set_exclude() and
break out from wait_event_interruptible and resume open.
Now use rws
Open exclusive check is protected by o_sem, no need sg_open_exclusive_lock.
@exclude is used to record which type of rwsem we are holding.

There is a race when open sg with O_EXCL flag. Also a race may happen between
sg_open and sg_remove.
Changes from v6:
* [1/4] remove double if.
* [3/4] fix via IS_ERR
Changes from v5:
Patches based on v3.11-rc7 and passed sg_tst_excl test.
* [1/4] * remove unused variables - res,sdp.
Push file descriptor list locking down to per-device locking. Let sg_index_lock
only protect device lookup.
sdp->detached is also set and checked with this lock held.
Changes from v4:
* Since I use ERR_PTR and friends in sg_add_sfp, this patch should also be
updated to resolve conflict in cherrry
@detached is set under the protection of sg_index_lock. Without getting the
lock, new sfp will be added during sg removal and there is no chance for it
to be picked out. So check with sg_index_lock held in sg_add_sfp().
Changes from v6:
* fix via IS_ERR
Changes from v5:
* remove sem_out label.

Joseph Lo reported a lockup on Tegra20 caused
by a race condition in coupled cpuidle. When two or more cpus
enter idle at the same time, the first cpus to arrive may go to the
ready loop without processing pending pokes from the last cpu to
arrive.
This patch adds a check for pending pokes once
Just FYI: I've merged two preparatory patches in my tree for the whole
lockref thing. Instead of applying your four patches as-is during the
merge window, I ended up writing two patches that introduce the
concept and use it in the dentry code *without* introducing any of the
new semantics yet.

Hi,
I am happy to see that dm-lc is picked up by LWN.
http://lwn.net/Articles/562938/
Now I think I should consider the next step forward.
As Joe Thornber said before, what I have to do next are
1. Get some feedback from 3rd party users.
2. Reviewed by Mike Snitzer.

pgoff is not used after the statement "pgoff = vma->vm_pgoff;",
so the assignment is redundant.

This patch improves the foreground gc efficiency by optimizing the
victim selection policy. With this optimization, the random re-write
performance could increase up to 20%.
For f2fs, foreground gc happens when disk is lack of free spaces,
it selects dirty segments and moves valid b
