Hi all,
I found that when we release eq->kobj by invoking kobject_put() we had gave
misson to workqueue, so that workqueue will release the elevator queue
space in elevator_alloc() which is registered in ->release of elv_ktype object.
We should not release it again.
So, this fix is wrong, please

In order to start reducing the duplicated code/constants/macros in this

add_disk() does not return an error status, but it can
still fail if there are problems elsewhere.
In particular a recent problem caused bdi_register_dev()

ACPI will manage WiFi chip's power state during suspend/resume

It's just a variant of wait_event_cmd, with exclusive flag being set.
For cases like RAID5, which puts many processes to sleep until 1/4

there is one process being able to get the resource as it's protected

contexnt primitives of kernel such as soft interupts, scheduling,
tasklet are implemented for libos. these functions eventually call the
functions registered by lib_init() API as well.

This is the 4th version of Linux LibOS patchset which reflects a
couple of comments received from people.
changes from v3:
- Patch 09/10 ("lib: libos build scripts and documentation")
1) Remove RFC (now it's a proposal)
2) build environment cleanup (commented by Paul Bolle)
- Overall
3) change
add SLIB allocator for arch/lib (CONFIG_LIB) to wrap kmalloc and co.
This will bring user's own allocator of libos: malloc(3) etc.

Hi Eduardo and Lukasz,
I checked this patch merged on linux-next.git.
But, this patch is not merged on Linux 4.1-rc1.
Thanks,

It's been a normal merge window, and I'm releasing according to the
normal schedule. The few days of travel didn't seem to matter, as I
had internet access at all times.
The merge window is pretty normal in terms of what got merged too.
Just eyeballing the size, it looks like this is going to fit
Hi,
Thanks for your comments :)

Just a heads-up to the x86 people: I'm going to merge this directly,
since I'm doing -rc1 momentarily, and without this patch 32-bit
user-land on a 64-bit kernel is flaky on all AMD CPU's. Which I don't
want for -rc1.

Hi Linus,
playing the race -rc1 game, nothing too urgent if this doesn't get in
though, Jani sent it after I started my weekend so I felt I should send
it on.
Just intel fixes 3 of them.

AMD CPUs don't reinitialize the SS descriptor on SYSRET, so SYSRET
with SS == 0 results in an invalid usermode state in which SS is
apparently equal to __USER_DS but causes #SS if used.
Work around the issue by setting SS to __KERNEL_DS __switch_to, thus
ensuring that SYSRET never happens with SS
