This (and the preceding) patch basically re-implemented the RCU
mechanisms of patch 784544739a25. That patch was replaced because of the
performance problems that it created when replacing tables. Now, we have
the same issue: the call
When a new table value was assigned, it was followed by a write memory
barrier. This ensured that all writes before this point would complete
before any writes after this point. However, to determine whether the

Currently the kernel adds the page, allocated for swapin, to the
swapcache before charging the page. This is fine but now we want a
per-memcg swapcache stat which is essential for folks who wants to

The behaviour of try_to_unmap_one() is difficult to follow because it
performs different operations based on a fairly large set of flags used
in different combinations.
TTU_MUNLOCK is one such flag. However it is exclusively used by
try_to_munlock() which specifies no other flags. Therefore

Some devices require exclusive write access to shared virtual

operations are occurring.
In order to do this introduce a new swap entry

Some NVIDIA GPUs do not support direct atomic access to system memory
via PCIe. Instead this must be emulated by granting the GPU exclusive
access to the memory. This is achieved by replacing CPU page table

Both migration and device private pages use special swap entries that
are manipluated by a range of inline functions. The arguments to these
are somewhat inconsitent so rework them to remove flag type arguments
and to make the arguments similar for both read and write entry
creation.
Call mmu_interval_notifier_insert() as part of nouveau_range_fault().
This doesn't introduce any functional change but makes it easier for a
subsequent patch to alter the behaviour of nouveau_range_fault() to
support GPU atomic operations.

Hello,
I am seeing the following call trace on the second run of "rtcwake -m mem -s
20".
After reverting commit 6f82b2558735 ("ixgbe: use generic power management"),
the call trace disappeared.
It seems "pci_disable_device()" is used in "__ixgbe_shutdown()", however
"pci_enable_device_mem()"

The code you looked at was based on that.
However, the virtio TC prefer not to mirror it. They have some concerns.

There're two features missing in current manpage, namely:
(1) Userfaultfd Thread-ID feature
(2) Userfaultfd write protect mode
There's also a 3rd one which was just contributed from Axel - Axel, I think it
would be great if you can add that part too, probably after the whole

Add an I2C bus driver for virtio para-virtualization.
The controller can be emulated by the backend driver in
any device model software by following the virtio protocol.
The device specification can be found on

There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].
