Certain files, when moved to another process have metadata changed, such
as netprioidx, and classid. This is the default behaviour in sending
sockets with SCM_RIGHTS over unix sockets. Depending on the usecase,
this may or may not be desirable with the addfd ioctl. This allows
the user to opt-in.
This introduces another call to addfd, in which the move flag is set. It
may make sense to setup a cgroup v1 hierarchy, and check that the
netprioidx is changed.

So if rc6 was a bit bigger than I would have liked, rc7 looks very

Plain "git log" never simplifies anything at all.

The variable ret is being initialized with a value that is
never read and it is being updated later with a new value. The
initialization is redundant and can be removed.

No. It's only completely accidentally like full-history

The zcomp driver uses per-CPU compression. The per-CPU data pointer is
acquired with get_cpu_ptr() which implicitly disables preemption.
It allocates memory inside the preempt disabled region which conflicts
with the PREEMPT_RT semantics.
Replace the implicit preemption

send_msg() disables preemption to avoid out-of-order messages. As the
code inside the preempt disabled section acquires regular spinlocks,
which are converted to 'sleeping' spinlocks on a PREEMPT_RT kernel and
eventually calls into a memory allocator, this conflicts with the
From: Ingo Molnar
The various struct pagevec per CPU variables are protected by disabling
either preemption or interrupts across the critical sections. Inside
these sections spinlocks have to be acquired.
These spinlocks are regular spinlock_t types which are converted to

From: Julia Cartwright
The squashfs multi CPU decompressor makes use of get_cpu_ptr() to
acquire a pointer to per-CPU data. get_cpu_ptr() implicitly disables
preemption which serializes the access to the per-CPU data.
But decompression can take quite some time depending on the size. The

preempt_disable() and local_irq_disable/save() are in principle per CPU big

- The protection scope is unknown
- Violation of protection rules is hard to detect by instrumentation
- For PREEMPT_RT such sections, unless in
zcomp::stream is per-CPU pointer, pointing to struct zcomp_strm which
contains two pointer. Having struct zcomp_strm allocated directly as
per-CPU memory would avoid one additional memory allocation and a
pointer dereference.
This also also simplifies adding a local_lock to struct zcomp_strm.
