+Subject: [PATCH 135/323] tasklets: Use spin wait in tasklet_disable()
+ temporarily
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.204-rt100.tar.xz
+
+To ease the transition use spin waiting in tasklet_disable() until all
+usage sites from atomic context have been cleaned up.
