[PATCH v3 0/1] x86/shstk: don't create the shadow stack for PF_USER_WORKERs

Posted by Oleg Nesterov 4 weeks, 1 day ago

Dave, et al, please review.

Our discussion with Rick was confusing and we can't convince each other.
Perhaps this is my fault. So let me resend 4/5 from this series

	[PATCH v2 0/5] x86/fpu: don't abuse x86_task_fpu(PF_USER_WORKER) in .regset_get() paths
	https://lore.kernel.org/all/20250822153603.GA27103@redhat.com/

as a separate patch. I tried to update the changelog.

Again, to me it looks like a simple cleanup which makes sense regardless,
but please correct me if I am wrong.

Oleg.
