Subject: [dpdk-dev] [PATCH 1/3] mem: fix index for unmapping segments on failure
Date: Thu, 3 May 2018 11:11:25 +0100 [thread overview]
Message-ID: <556d606e3af8ab32e920611d166a0154e472fe25.1525342009.git.anatoly.burakov@intel.com> (raw)
Segment index was calculated incorrectly, causing free_seg to
attempt to free segments that do not exist.
Fixes: a5ff05d60fc5 ("mem: support unmapping pages at runtime")
