Subject: [PATCH 1/1] btrfs-progs: fix compiler warning
From: Christian Hesse <mail@xxxxxxxx>
To: linux-btrfs@xxxxxxxxxxxxxxx

gcc 4.9.0 gives a warning: array subscript is above array bounds
Checking for "greater or equal" instead of just "equal" fixes this.

Also I faied to reproduce the bug.
Using gcc-4.9.0-3 from Archlinux core repo.
It seems to be related to default gcc flags from distribution?
Thanks,
