Subject: [PATCH v3 1/8] padata: remove exit routine
Date: Wed, 27 May 2020 13:36:01 -0400 [thread overview]
Message-ID: <20200527173608.2885243-2-daniel.m.jordan@oracle.com> (raw)
In-Reply-To: <20200527173608.2885243-1-daniel.m.jordan@oracle.com>
padata_driver_exit() is unnecessary because padata isn't built as a
module and doesn't exit.
padata's init routine will soon allocate memory, so getting rid of the
exit function now avoids pointless code to free it.
