Subject: [PATCH] tests/intel/xe_vm: fix double munmap of first mapping
Date: Mon, 31 Aug 2026 16:29:28 +0000 [thread overview]
Message-ID: <20260831162928.201586-1-nishit.sharma@intel.com> (raw)
From: Nishit Sharma <nishit.sharma@intel.com>
In the cleanup path of the bind-array conflict test, when a second buffer
object mapping (map2) exists, the code called munmap() on the first
mapping (map) a second time instead of unmapping map2:
This double-unmaps the map region while leaking the map2 mapping entirely.
