Subject: [PATCH 13/22] coda: get rid of CODA_FREE()
Date: Fri, 17 May 2019 14:36:51 -0400	[thread overview]
Message-ID: <4950a94fd30ec5f84835dd4ca0bb67c0448672f5.1558117389.git.jaharkes@cs.cmu.edu> (raw)
In-Reply-To: <cover.1558117389.git.jaharkes@cs.cmu.edu>

From: Dan Carpenter <dan.carpenter@oracle.com>

The CODA_FREE() macro just calls kvfree().  We can call that directly
instead.
