Subject: [PATCH v6 10/15] selftests/nolibc: prepare: create /dev/zero
Date: Fri, 7 Jul 2023 23:02:16 +0800 [thread overview]
Message-ID: <589b6a374e604b6289eb00890cd63e2b7d2ce86f.1688739492.git.falcon@tinylab.org> (raw)
In-Reply-To: <cover.1688739492.git.falcon@tinylab.org>
/dev/zero is commonly used to allocate anonymous memory, it is a very
good file for tests, let's prepare it.
