Subject: [PATCH 8/8] tests/9pfs: add local unlinkat hard link test
Date: Tue, 20 Oct 2020 01:13:24 +0200 [thread overview]
Message-ID: <63a6783a516398a55a8e91dd678d3926abb7e138.1603149434.git.qemu_oss@crudebyte.com> (raw)
In-Reply-To: <cover.1603149434.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.
