From: Anatoly Burakov Date: Tue, 17 Apr 2018 10:57:52 +0000 (+0100) Subject: mem: log page address before unmapping X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=8f91f368a1e3cf078cc702794c3669f18d27311c;p=dpdk.git mem: log page address before unmapping If user has specified a flag to unmap the area right after mapping it, we were passing an already-unmapped pointer to RTE_LOG. This is not an issue since RTE_LOG doesn't actually dereference the pointer, but fix it anyway by moving call to RTE_LOG to before unmap.
