  # HEAD: f946cae86d088d02a2f9c0ae0bf8a80359d3f454: scftorture: Handle NULL argument passed to scf_add_to_free_list(). (2024-11-14 16:09:51 -0800)

----------------------------------------------------------------
scftorture changes for v6.13

o	Avoid divide operation.

o	Fix cleanup code waiting for IPI handlers.

o	Move memory allocations out of preempt-disable region of code
	for PREEMPT_RT compatibility.

o	Use a lockless list to avoid freeing memory while interrupts
	are disabled, again for PREEMPT_RT compatibility.

o	Make lockless list scf_add_to_free_list() correctly handle
	freeing a NULL pointer.
