From 00b3c11879d790f51cac6477abe870936a2323ae Mon Sep 17 00:00:00 2001 From: Allen Pais Date: Thu, 3 Sep 2020 11:36:37 +0530 Subject: [PATCH] RDMA/rxe: 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.
