(CVE-2022-21123)

For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE

Bug Fix(es):

* SolarFlare sfc spurious TX completion

* Page allocation failure on cryptsetup open

* The kernel-rt crashes where one task is indefinitely looping in
__start_cfs_bandwidth() with the cfs_b->lock spinlock being held

* While using PTimekeeper the qede driver produces excessive log messages

* The kernel crashes due to a GPF happens in mutex_spin_on_owner(). The
known RDMA/cma bug that was introduced with a patch from upstream commit
722c7b2bfead is the possible cause.

* Running LTP testcase creat09 fails showing related  to 'cve-2018-13405'
