4.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
[ Upstream commit 50c2e4dd6749725338621fff456b26d3a592259f ]
The > should be >=. I also added spaces around the '-' operations so
the code is a little more consistent and matches the condition better.
Fixes: f53c3fe8dad7 ('xen-netback: Introduce TX grant mapping')
