Subject: [PATCH v2 6/7] KVM: selftests: Allocate ucall pool from MEM_REGION_DATA
Date: Fri, 9 Dec 2022 01:53:05 +0000 [thread overview]
Message-ID: <20221209015307.1781352-7-oliver.upton@linux.dev> (raw)
In-Reply-To: <20221209015307.1781352-1-oliver.upton@linux.dev>
MEM_REGION_TEST_DATA is meant to hold data explicitly used by a
selftest, not implicit allocations due to the selftests infrastructure.
Allocate the ucall pool from MEM_REGION_DATA much like the rest of the
selftests library allocations.
