Subject: [PATCH AUTOSEL 4.19 019/671] IB/rxe: replace kvfree with vfree
Date: Thu, 16 Jan 2020 11:44:10 -0500
Message-ID: <20200116165502.8838-19-sashal@kernel.org> (raw)
In-Reply-To: <20200116165502.8838-1-sashal@kernel.org>

From: Zhu Yanjun <yanjun.zhu@oracle.com>

[ Upstream commit 721ad7e643f7002efa398838693f90284ea216d1 ]

The buf is allocated by vmalloc_user in the function rxe_queue_init.
So it is better to free it by vfree.

Fixes: 8700e3e7c485 ("Soft RoCE driver")
