Subject: [PATCH] tests/tcg: Extend file in linux-madvise.c
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When guest page size > host page size, this test can fail
due to the SIGBUS protection hack. Avoid this by making
sure that the file size is at least one guest page.
Visible with alpha guest on x86_64 host.
