Subject: [PATCH 4/6] fs: Remove O_TRUNC check for devices when open files
Date: Fri, 25 Nov 2016 09:06:05 +0100	[thread overview]
Message-ID: <1480061167-21590-5-git-send-email-t.remmet@phytec.de> (raw)
In-Reply-To: <1480061167-21590-1-git-send-email-t.remmet@phytec.de>

Don't check for the file type here. Devices may have truncate
callbacks. Otherwise the caller should check if O_TRUNC is possible.
