Hello All,
These are ilock patches which helps improve the current inode lock scalabiliy
problem in ext4 DIO mixed-read/write workload case. The problem was first
reported by Joseph [1]. These patches are based upon upstream discussion
with Jan Kara & Joseph [2].
Since these patches introduce
Earlier there was no shared lock in DIO read path.
But this patch (16c54688592ce: ext4: Allow parallel DIO reads)
simplified some of the locking mechanism while still allowing
for parallel DIO reads by adding shared lock in inode DIO
read path.
But this created problem with mixed read/write

The existing gup code does not react to the fatal signals in many code
paths. For example, in one retry path of gup we're still using
down_read() rather than down_read_killable(). Also, when doing page
faults we don't pass in FAULT_FLAG_KILLABLE as well, which means that
within the faulting
The idea comes from a discussion between Linus and Andrea [1].
Before this patch we only allow a page fault to retry once. We
achieved this by clearing the FAULT_FLAG_ALLOW_RETRY flag when doing
handle_mm_fault() the second time. This was majorly used to avoid
unexpected starvation of the
This is the gup counterpart of the change that allows the
VM_FAULT_RETRY to happen for more than once. One thing to mention is
that we must check the fatal signal here before retry because the GUP
can be interrupted by that, otherwise we can loop forever.

Userfaultfd fault path was by default killable even if the caller does
not have FAULT_FLAG_KILLABLE. That makes sense before in that when

after previous patch we've got FAULT_FLAG_KILLABLE applied even for

A summary to the issue: there was a special path in handle_userfault()
in the past that we'll return a VM_FAULT_NOPAGE when we detected
non-fatal signals when
This patch removes the risk path in handle_userfault() then we will be
sure that the callers of handle_mm_fault() will know that the VMAs
might have changed. Meanwhile with previous patch we don't lose
responsiveness as well since the core mm code now can handle the
nonfatal userspace signals
There's plenty of places around __get_user_pages() that has a parameter
"nonblocking" which does not really mean that "it won't block" (because
it can really block) but instead it shows whether the mmap_sem is
released by up_read() during the page fault handling mostly when
VM_FAULT_RETRY is
When follow_hugetlb_page() returns with *locked==0, it means we've got
a VM_FAULT_RETRY within the fauling process and we've released the
mmap_sem. When that happens, we should stop and bail out.

This is the 4th version of the PF enhancement series on signal
handlings and fault retries. This new version does not change
existing patches in v3 but added two more patches to address the
current gup issue on not responding to SIGKILL. A 3rd new patch is
also added to allow handle_userfaultfd
handle_userfaultfd() is currently the only one place in the kernel
page fault procedures that can respond to non-fatal userspace signals.
It was trying to detect such an allowance by checking against USER &
KILLABLE flags, which was "un-official".
In this patch, we introduced a new flag
Although there're tons of arch-specific page fault handlers, most of
them are still sharing the same initial value of the page fault flags.
Say, merely all of the page fault handlers would allow the fault to be
retried, and they also allow the fault to respond to SIGKILL.

For the kernel space, all ebreak instructions are determined at compile

There seems to be some new features/cleanups
There is no need to re-configure PLLX if its configuration in unchanged
on return from suspend / cpuidle, this saves 300us if PLLX is already
enabled (common case for cpuidle).

Attemping to make my CI20 more usefull than a paperweight, I add nodes to
Devicetree, at this time:
- The IW8103 need some work to stay alive because power seem to turn off.
- The leds patch lack of correct option in ci20_defconfig.
- The Cpu patch isn't usefull without SMP support of jz4780.
