Subject: [PATCH liburing v5 08/10] test: Add nolibc test
Date: Tue,  5 Jul 2022 14:43:58 +0700	[thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>

From: Ammar Faizi <[email protected]>

Test liburing nolibc functionality. The first use case of this test is
to test get_page_size() function as we don't seem to have a test that
tests this path. This is especially important for aarch64 because we
rely on reading /proc/self/auxv rather than hard coding it like what we
do for x86 and x86-64. We may add more nolibc tests in this file in the
future.
