From 6e1978a9a941d342a8b2e6432f52e07d4af86e21 Mon Sep 17 00:00:00 2001 From: Allen Pais Date: Tue, 3 Nov 2020 14:48:21 +0530 Subject: [PATCH] net: sched: convert tasklets to use new tasklet_setup() API In preparation for unconditionally passing the struct tasklet_struct pointer to all tasklet callbacks, switch to using the new tasklet_setup() and from_tasklet() to pass the tasklet pointer explicitly.
