Subject: [PATCH v2 8/8] tests/9pfs: add local Tunlinkat hard link test
Date: Wed, 21 Oct 2020 14:55:46 +0200 [thread overview]
Message-ID: <9bec33a7d8f006ef8f80517985d0d6ac48650d53.1603285620.git.qemu_oss@crudebyte.com> (raw)
In-Reply-To: <cover.1603285620.git.qemu_oss@crudebyte.com>
This test case uses a Tunlinkat request to remove a previously hard
linked file by using the 9pfs 'local' fs driver.
