Hello,
Is it possible to print the timeout value in character driver poll() API?
User mode call: int poll(struct pollfd *fds, nfds_t nfds, int timeout)
Kernel mode call: unsigned int driver_poll(struct file *filp, poll_table *wait)

Same as before. Strange error with fuse trying to load (I think its
related in some way with the writes being made to the /proc/sysrq),
then strange errors. I am running on CENTOS 6.3 with 4.2.4 kernel.
fsck cleans up the problem so its not a disk error, kernel error of
some sort.

Thanks for your review.
I did the test and it seems that it should be ok when CONFIG_PM is not defined.
So I removed the protection code to make it more readable.
Do you think is it ok?

This is really about simplifying the double xchg patterns into
a single cmpxchg, with the same logic. Other than the immediate
cleanup, there are some subtleties this change deals with:
(i) While the load of the old bt is fully ordered wrt everything,
ie:
old_bt = xchg(&q->blk_trace, bt);
By extending the syntax of BPF object section names, this patch allows
user to attach BPF programs to symbol in modules. For example:
SEC("module=i915\n"
"parse_cmds=i915_parse_cmds")
int parse_cmds(void *ctx)
{
return 1;
}
Implementation is very simple: like what 'perf probe' does,

Here's a v2 that fixes a problem in --per-core mode.

Add a new mode to only print metrics. Sometimes we don't care about
the raw values, just want the computed metrics. This allows more
compact printing, so with -I each sample is only a single line.
This also allows easier plotting and proces
What if we have a git_fallback "auto" mode which only falls back to

Commit 073db4a51ee4 ("mtd: fix: avoid race condition when accessing
mtd->usecount") fixed a race condition but due to poor ordering of the
mutex acquisition, introduced a potential deadlock.
The deadlock can occur, for example, when rmmod'ing the m25p80 module, which
will delete one or more MTDs,
It seems more logical to use a device node directly associated with the
MTD master device (i.e., mtd->dev.of_node field) rather than requiring
auxiliary partition parser information to be passed in by the driver in
a separate struct.
This patch supports the mtd->dev.of_node field, deprecates the p

Hi Boqun,
Can you please split this into two patches. One that does the cmpxchg change
and one that changes PPC_ATOMIC_ENTRY_BARRIER.

Now that the SPI-NOR/MTD framework pass the 'flash_node' through to the
partition parsing code, we don't have to do it ourselves.
Also convert to mtd_device_register(), since we don't need the 2nd and
3rd parameters anymore.

We should assign the MTD dev.of_node instead of the parser data field.
This gets us the equivalent partition parser behavior with fewer special
fields and parameter passing.
Also convert several of these to mtd_device_register(), since we don't
need the 2nd and 3rd parameters anymore.

Hi,
I noticed that, for MTD drivers that want to support DT partition parsing
(essentially all recent ones), it's a bit awkward to set the tell MTD which DT
node to use. I also noticed that this info is duplicated in a few places;
namely, some sub-subsystems (like SPI NOR and NAND) need their own
All of these drivers set up a parser data struct just to communicate DT
partition data. This field has been deprecated and is instead supported
by telling nand_scan_ident() about the 'flash_node'.
