Message-Id: <1472069000-18897-5-git-send-email-fabf@skynet.be>
Date: Wed, 24 Aug 2016 22:03:18 +0200
From: Fabian Frederick <fabf@...net.be>
To: tytso@....edu, Andreas Dilger <adilger.kernel@...ger.ca>
Cc: linux-ext4@...r.kernel.org, linux-kernel@...r.kernel.org,
fabf@...net.be
Subject: [PATCH 4/6 linux-next] ext4: use bool for check in ext4_ext_space_()
check is used in 0/1 context.
Also use unsigned int instead of unsigned (checkpatch warning)
