Iterating over a property containing a list of phandles with arguments
is a common operation for device drivers. This patch adds a new
of_property_for_each_phandle_with_args() macro to make the iteration
simpler.

Hello,
This patchset tries to remove all die() calls in event filter parsing
code. I changed two main functions of pevent_filter_add_filter_str()
and pevent_filter_match() to return a proper error code (pevent_errno).
The actual error message might be saved in a static buffer in pevent_
filter a
Also check return value and handle it.

From: Namhyung Kim
The pevent_filter_strerror() function is for receiving actual error
message from pevent_errno value. To do that, add a static buffer to
event_filter for saving internal error message
If a failed function saved other information in the static buffer
returns the information, ot
Those functions are for stringify filter arguments. As caller of
those functions handles NULL string properly, it seems that it's
enough to return NULL rather than calling die().

The immediate problem I see with setting aside reserves "off the top"
is that we don't really know a priori how much memory the kernel
itself is going to use, which could still land us in an overcommitted
state.

The return values of seq_printf/puts/putc are frequently misused.
Start down a path to remove all the return value uses of these
functions.
Make the static bool seq_overflow public along with a rename of
the function to seq_is_buf_full. Rename the still static
seq_set_overflow to seq_set_buf_ful
Since adding a new function to seq_file (seq_is_buf_full)
there isn't any value for functions called from seq_show to
return anything. Remove the int returns of the various
print_tuple/_print_tuple functions.

Hi Jens,
Today's linux-next merge of the block tree got a conflict in
fs/f2fs/data.c between commit 8758e549e105 ("f2fs: add unlikely() macro
for compiler more aggressively") from the f2fs tree and commit
2c30c71bd653 ("block: Convert various code to bio_for_each_segment()")
from the block tree.

When a controlling tty is being hung up and the hang up is
waiting for a just-signalled tty reader or writer to exit, and a new tty
reader/writer tries to acquire an ldisc reference concurrently with the
ldisc reference release from the signalled reader/writer, the hangup
can hang. The new reader/w

I know it's late in the -rc cycle but I'd like to get this fix into 3.13.
Although it's only likely to happen at shutdown/reboot, the hang frequency
could be as often as 1 in 1.
The patch fixes the count value returned when the cmpxchg() has
successfully changed the count. Only one code
This patch introduces new sysfs entries for users to control the policy of
in-place-updates, namely IPU, in f2fs.
Sometimes f2fs suffers from performance degradation due to its out-of-place
update policy that produces many additional node block writes.

We should probably have a more detailed description of when to use
simple wait queues verses normal wait queues. These are obviously much
lighter wait, and should be the pref
