[PATCHSET 0/3] Ring resizing fixes

[Jens Axboe <axboe@kernel.dk>]

Hi,

A few fixes for the ring resizing that should go into 6.13. Note that
this doesn't impact other kernels, as the ring resizing was added in
this release.

Patch 1 fixes an issue with malicious userspace modifying the ring
memory while a resize operation is in progress. Patch 2 modifies the
shared memory reading to use read/write once, as is appropriate, and
finally patch 3 ensures the CQ/SQ ring heads are only read once and
that the validated value is used for the copies.
