[LTP] [PATCH v2 09/16] controllers: Update cgroup_fj_* to use newer cgroup lib and test lib
Luke Nowakowski-Krijger
luke.nowakowskikrijger@canonical.com
Sat Mar 5 00:18:19 CET 2022
Update the cgroup_fj_* tests to use the newer test lib and to use the
updated version of the cgroup lib which handles mounting and unmounting
for both v1 and v2 controllers.
The tests were modified to accommodate testing the v2 controller
interfaces where it still made sense, and in other places tests were
skipped as they were testing using specific parts of the v1 interface
that doesn't exist on v2 controllers.
Also updated the licensing info at the beginning of the file with SPDX
license identifier.
Signed-off-by: Luke Nowakowski-Krijger <luke.nowakowskikrijger@canonical.com>

v2: Remove exist_subsystem() function.
Correct spelling mistakes in commit message.
Change version numbers to "2" instead of "v2"
