The ABI documentation indicates that field separators do not need a
space between them, only a ';'. When no spacing is used, the register
must work. Any subsequent register, with or without spaces, must match
and not return -EADDRINUSE.
Add a non-spacing separator case to our self-test register
When the ABI was updated to prevent same name w/different args, it
missed an important corner case when fields don't end with a space.
Typically, space is used for fields to help separate them, like
"u8 field1; u8 field2". If no spaces are used, like
"u8 field1;u8 field2", then the parsing works

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.

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.

Commit c05ae9d85b47 ("dax/bus.c: replace driver-core lock usage by a local

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 [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.

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

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
