kernel: scsi: qedf: Make qedf_execute_tmf() non-preemptible

A vulnerability was found in the Linux kernel's qedf driver function qedfexecutetmf, where the function call smpprocessorid is done from preemptible code before acquiring a lock which can result in BUGON when running an RT kernel. This can result in system inconsistencies...

UBUNTU-CVE-2024-50138

In the Linux kernel, the following vulnerability has been resolved: bpf: Use rawspinlockt in ringbuf The function bpfringbufreserve is invoked from a tracepoint, which disables preemption. Using spinlockt in this context can lead to a "sleep in atomic" warning in the RT variant. This issue is...
