Subject: [PATCH] btrfs/022: Add qgroup assign test
Date: Sun, 20 Sep 2020 08:57:53 +0000 [thread overview]
Message-ID: <20200920085753.277590-1-realwakka@gmail.com> (raw)
The btrfs/022 test is basic test about qgroup. but it doesn't have
test with qgroup assign function. This patch adds parent assign
test. parent assign test make two subvolumes and a qgroup for assign.
Assign two subvolumes with a qgroup and check that quota of group
has same value with sum of two subvolumes.
