drm_put_dev also calls drm_dev_unregister, so dev will be unregistered
twice.
Replace it with drm_dev_put to fix it.

The '[smp_]read_barrier_depends()' macros no longer exist, so we don't
need to deal with them in the checkpatch script.

'smp_read_barrier_depends()' doesn't exist any more, so reword the two
comments that mention it to refer to "dependency ordering" instead.

There are no remaining users of '[smp_]read_barrier_depends()', so
remove it from the generic implementation of 'barrier.h'.

The '[smp_]read_barrier_depends()' barrier macros no longer exist as

the Documentation/ directory.
Although this is fairly mechanical on the whole, we drop the "CACHE

Alpha overrides '__read_once_size_n()' directly, so there's no need to

Rather then relying on the core code to use 'smp_read_barrier_depends()'
as part of the 'READ_ONCE()' definition, instead override 'READ_ONCE()'
in the Alpha code so that it is treated the same way as
'smp_load_acquire()'.

In preparation for allowing architectures to define their own
implementation of the 'READ_ONCE()' macro, move the generic
'{READ,WRITE}_ONCE()' definitions out of the unwieldy 'linux/compiler.h'
and into a new 'rwonce.h' header under 'asm-generic'.

Hi all,
Although [smp_]read_barrier_depends() became part of READ_ONCE() in
commit 76ebbe78f739 ("locking/barriers: Add implicit
smp_read_barrier_depends() to READ_ONCE()"), it still limps on in the
Linux memory model with the sinister hope of attracting innocent new
users so that it becomes
The '__READ_ONCE_SIZE()' macro is only used as part of building
'READ_ONCE()', so undefine it once we don't need it anymore.

The meat and potatoes of 'READ_ONCE()' is defined by the
'__READ_ONCE_SIZE()' macro, which uses volatile casts in an attempt to
avoid tearing of byte, halfword, word and double-word accesses. Allow
this to be overridden by the architecture code in the case that things
like memory barriers are also
Since commit 76ebbe78f739 ("locking/barriers: Add implicit
smp_read_barrier_depends() to READ_ONCE()"), there is no need to use
'smp_read_barrier_depends()' outside of the Alpha architecture code.
Unfortunately, there is precisely >one< user in the vhost code, and

The "42f5cda5eaf4" commit rightly set SOCK_DONE on peer shutdown,

In this case, when the timeout fires, the SOCK_DONE is already
set and the virtio_transport_close_timeout() will not
