Subject: [PATCH 5/7] kernel: cobalt: support building against v5.0
Date: Tue,  5 Mar 2019 16:45:19 +0200	[thread overview]
Message-ID: <20190305144521.2567-5-roman.stratiienko@globallogic.com> (raw)
In-Reply-To: <20190305144521.2567-1-roman.stratiienko@globallogic.com>

From: Roman Stratiienko <roman.stratiienko@globallogic.com>

Since kernel v5.0 upstream commit 96d4f267e40f
("Remove 'type' argument from access_ok() function")
 access_ok() funcion takes only 2 parameters

Change access_rok and access_wok wrappers for kernels
 starting from v5.0, and preserve them for earlier versions
