Even though QDF2400 supports MSI interrupts with SMMUv3, it is not enabled
in ACPI FW to preserve compatibility with older kernel versions. Code is
emitting warning message during boot.
This is causing some test tools to record a false warning and is causing
support issues.

The upcoming aio poll support would like to be able to complete the

a lock order reversal. Add support for optionally moving the cancelation
outside the context lock to avoid this reversal.

Simple one-shot poll through the io_submit() interface. To poll for
a file descriptor the application should submit an iocb of type
IOCB_CMD_POLL. It will poll the fd for the events specified in the
the first 32 bits of the aio_buf field of the iocb.
Unlike poll or epoll without EPOLLONESHOT thi

This is the io_getevents equivalent of ppoll/pselect and allows to
properly mix signals and aio completions (especially with IOCB_CMD_POLL)
and atomically executes the following sequence:

Instead of handcoded non-null checks always initialize ki_list to an
empty list and use list_empty / list_empty_careful on it. While we're
at it also error out on a double call to kiocb_set_cancel_fn instead
of ignoring it.

Don't reference the kiocb structure from the common aio code, and move
any use of it into helper specific to the read/write path. This is in
preparation for aio_poll support that wants to use the space for different
fields.

These days we don't treat sync iocbs special in the aio completion code as
they never use it. Remove the old comment, and move the BUG_ON for a sync
iocb to the top of the function.

Honestly, I think we should apply that patch regardless.
Using 'wbinvd' should not be some "just because of random reasons".

These and the ->aio_fsync method had been merged together with the
initial aio support, but no ->aio_fsync method had ever been implemented
in mainline, so it got removed a while ago.
This patch wires up the iocb commands to a simple workqueue based offload
that already shows great performance. I
Hi all,
this patch adds workqueue based fsync offload. Version of this
patch have been floating around for a couple years, but we now
have a user with seastar used by ScyllaDB (who sponsored this
work) that really wants this in addition to the aio poll support.
More details are in the patch itsel

That should be "some of the errata around wbinvd". I have no idea if
