Subject: [PATCH 04/13] fstests: add tool migrate group membership data to test files
Date: Tue, 08 Jun 2021 10:19:44 -0700	[thread overview]
Message-ID: <162317278412.653489.8220326541398463657.stgit@locust> (raw)
In-Reply-To: <162317276202.653489.13006238543620278716.stgit@locust>

From: Darrick J. Wong <djwong@kernel.org>

Create a tool to migrate the mapping of tests <-> groups out of the
group file and into the individual test file as a _begin_fstest
call.  In the next patches we'll rewrite all the test files and auto
generate the group files from the tests.
