Subject: [PATCH 7/8] net: smc: convert tasklets to use new tasklet_setup() API
Date: Mon, 17 Aug 2020 14:21:19 +0530	[thread overview]
Message-ID: <20200817085120.24894-7-allen.cryptic@gmail.com> (raw)
In-Reply-To: <20200817085120.24894-1-allen.cryptic@gmail.com>

From: Allen Pais <allen.lkml@gmail.com>

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.
