Subject: [PATCH 7/8] tests/9pfs: add local Tlink test
Date: Tue, 20 Oct 2020 01:13:24 +0200 [thread overview]
Message-ID: <ee6d9e1147d05bcf0b51b02ef6757f4b4691ba2d.1603149434.git.qemu_oss@crudebyte.com> (raw)
In-Reply-To: <cover.1603149434.git.qemu_oss@crudebyte.com>
This test case uses a Tlink request to create a hard link to a regular
file using the 9pfs 'local' fs driver.
