Hi,
as discussed before:
If a high-scalability locking scheme is built with multiple
spinlocks, then often additional memory barriers are required.
The documentation was not as clear as possible, and memory
barriers were missing / superfluous in the implementation.
Patch 1: Documentation, define
For x86 qspinlocks, no additional memory barrier is required in
smp_mb__after_spin_lock:
Theoretically, for qspinlock we could define two barriers:
- smp_mb__after_spin_lock: Free for x86, not free for powerpc
- smp_mb__between_spin_lock_and_spin_unlock_wait():
Free for all archs, see queu
Right now, the spinlock machinery tries to guarantee barriers even for
unorthodox locking cases, which ends up as a constant stream of updates
as the architectures try to support new unorthodox ideas.
The patch proposes to reverse that:
spin_lock is ACQUIRE, spin_unlock is RELEASE.
spin_unlock_wai
Change the locking for nf_conntrack_lock and nf_conntract_lock_all()
to the approach used by ipc/sem.c:
- use smp_store_mb() instead of a raw smp_mb()
- use smp_mb__after_spin_lock().
- for nf_conntrack_lock, use spin_lock(&global_lock) instead of
spin_unlock_wait(&global_lock) and loop backward
spin_unlock() + spin_lock() together do not form a full memory barrier:
a=1;
spin_unlock(&b);
spin_lock(&c);
+ smp_mb__after_unlock_lock();
d=1;
Without the smp_mb__after_unlock_lock(), other CPUs can observe the
write to d without seeing the write to a.

Hi,
These patches add tests for userfaultfd events used in non-cooperative
scenario.
The tests verify that fork(), mremap() and madvise(MADV_DONTNEED) can be
properly handled when the process that monitors userfaultfd is not the
process that causes the pagefaults.
Mike Rapoport (3):
userfaultfd
With future addition of event tests, copy_page will be called with
different userfault file descriptors

Also use the same changing to asm-generic, and also use bool variable

I'm doing it because this function is only used inside rtw_recv.c. Which
is quite logical, since it's a timer

Hi! Here is my second regression report for Linux 4.8. It lists 11
regressions. 5 of them are new; 5 mentioned in the last report two
weeks ago got fixed.
FWIW: A small detail: I did not include "Regression - SATA disks behind
USB ones on v4.8-rc1, breaking boot. [Re: Who reordered my disks]"

On some platforms, there is occasional panic triggered when trying to
resume from hibernation, a typical panic looks like:
"BUG: unable to handle kernel paging request at 880085894000
IP: [] load_image_lzo+0x8c2/0xe70"
This is because e820 map has been changed by BIOS across
hibernation, and
