Hi Eric,
After merging the userns tree, today's linux-next build (x86_64
allmodconfig) failed like this:
kernel/audit.c: In function 'audit_receive_msg':
kernel/audit.c:753:37: error: 'struct netlink_skb_parms' has no member named
'pid'
I missed the conflict between commit 35ce9888ad2a

Since we always pass flush responsibility to next, we will not deprive it,
now the ->first_flusher can only be changed by the first_flusher, no one
can change it, no race as 4ce48b37 said.
Remove the check introduced by 4ce48b37, use BUG_ON() instead.
Also move "wq->first_flusher = NULL;" later.
it is a helper to relase reference.
This patch doesn't make any functional difference.

Start all flusher at the same time(except the overflowed flushers).
Since we have nr_cwqs_to_flush array for each color, any flush
color can start the same time, every color don't interfere
each other. The progress of flushing for any color is the same
as the old code.
A little different is
depriving the responsibility make the code complex, we pass it to the next
unconditionally.
After this change, we don't need to go back to repeat cascading, so we use
"break" to exit the loop.
The loop will be remove in later patch.

We can detect whether a flusher is started by comparing its
flush_color VS wq->work_color.
We move all overflowed flusher to flusher_queue, and then we
start flush for them when there is freed color. we detect it
by the color of the last flusher of the flusher_queue.
This patch doesn't make any
wq->work_color is unchanged between overflowed flusher queued on
->flusher_overflow and requeued on ->flusher_queue.
So we can assign overflowed flushers's flush color when they are queued
on ->flusher_overflow.
This patch makes the flusher's flush color more clear:
flusher's flush
The core patch is patch6, it makes all flusher can start and the same time
and allow us do more cleanup.
Only patch1 and patch6 change the behavior of the code.
All other patches do not change any behavior.

Use wq->first_flusher->flush_color instead.
If current task is the first_flusher, we use @flush_color

Move the advance of wq->work_color into flush_workqueue_prep_cwqs()
and rename flush_workqueue_prep_cwqs() to workqueue_start_flush(),
It will simplify the caller.
Since the @flush_color and @work_color can't be -1, so we remove
the test in workqueue_start_flush() and fix the indent.

Hi all,
Today's linux-next merge of the arm-soc tree got a conflict in
drivers/video/omap/lcd_ams_delta.c between commit 9586778de558 ("OMAPFB1:
remove unnecessary includes") from the tree and commit e27e35ec735f
("ARM: OMAP1: Move board-ams-delta.h from plat to mach") from the arm-soc
tree.
The series tries to convert the i2c_msg to c99 struct.
This may avoid issues like below if someone tries to add a
structure.
