[PATCH] jump_label: Remove unused jump_label_rate_limit

From: linux
Date: Sat Jan 11 2025 - 09:29:44 EST


From: "Dr. David Alan Gilbert" <linux@xxxxxxxxxxx>

The last use of jump_label_rate_limit() was removed in 2021 by
commit 6e4e3b4df4e3 ("KVM: Stop using deprecated jump label APIs")

Remove it.
