The RSS hash report is a feature that's part of the virtio specification.

Let's make all IPVS sysctls visible and RO even when
network namespace is owned by non-initial user namespace.
Let's make a few sysctls to be writable:
- conntrack
- conn_reuse_mode
- expire_nodest_conn
- expire_quiescent_template
I'm trying to be conservative with this to prevent
introducing any

Hi Haitao,
I don't like to say but in general I think you are sending too
frequently. The

In [1], Dan points out that all of the WARN_ON_ONCE() usage in the
referenced patch should be replaced with lockdep_assert_held, or
lockdep_held_assert_write(). Replace these as appropriate.

Fix
Commit c05ae9d85b47 ("dax/bus.c: replace driver-core lock usage by a local
rwsem")
was a bit overzealous in eliminating device_lock() usage, and ended up
removing a couple of lock acquisitions which were needed, and as a
result, fix some of the conditional locking missteps that the above
commit in
In size_show(), the dax_dev_rwsem only needs a read lock, but was
acquiring a write lock. Change it to down_read_interruptible() so it
doesn't unnecessarily hold a write lock.

Change an instance of down_write_killable() to a simple down_write() where
there is no user process that might want to interrupt the operation.
