Subject: [dpdk-dev] [PATCH v2 06/10] mem: fix comparing pointer to value
Date: Wed, 18 Apr 2018 11:37:39 +0100	[thread overview]
Message-ID: <9ff005c6c19d34f39249d0ca3d187b4699a97de0.1524047073.git.anatoly.burakov@intel.com> (raw)
In-Reply-To: <cover.1524047073.git.anatoly.burakov@intel.com>
In-Reply-To: <cover.1524047073.git.anatoly.burakov@intel.com>

Previous code had an old rebase leftover from the time when
oldpolicy was an actual int, instead of a pointer. Fix it to
do comparison with dereferencing the pointer.

Coverity issue: 272589

Fixes: 582bed1e1d1d ("mem: support mapping hugepages at runtime")
