Add a cpu notifier to virtio-net, so that we can reset the
virtqueue affinity if the cpu hotplug happens. It improve
the performance through enabling or disabling the virtqueue
affinity after doing cpu hotplug.

Hi Tang,
I don't think it can work well.
The patch gets memory range of hotpluggable memory by
acpi_numa_memory_affinity_init(). But it too late.
For example, if we use log_buf_len boot options, memblock allocator
runs before getting SRAT information. In this case, this movablecore_map
boot option
sock->sk_cgrp_prioidx won't be used at all if CONFIG_NETPRIO_CGROUP=n.

When the WCE flag is set for a drive, sd_shutdown() and sd_suspend() try
to send a SYNCHRONIZE_CACHE command to that drive. This is not
meaningful when no media are present and causes errors with devices
where the media are the actual command processing devices, such as SATA

Since commit 89c8d91e31f2 ("tty: localise the lock") I see a dead lock
in one of my dummy_hcd + g_nokia test cases. The first run was usually
okay, the second often resulted in a splat by lockdep and the third was
usually a dead lock.
Lockdep complained about tty->
Hi list, Jens.
Please note that I'm a kernel newbie, hope I'm not about to embarrass myself.

Did you verify possibilities listed at

If so, a summary in the patchset would be helpful.

If memcg is enabled and no non-root memcg exists, all allocated pages

Similar to dirty page, we add per cgroup writeback pages accounting. The lock

mem_cgroup_end_update_page_stat()

It's inspired by a similar optimization from Glauber Costa

From: Sha Zhengju
While accounting memcg page stat, it's not worth to use MEMCG_NR_FILE_MAPPED
as an extra layer of indirection because of the complexity and presumed
performance overhead. We can use MEM_CGROUP_STAT_FILE_MAPPED directly.
