From codes POV, one function should be enough to do the same thing then
caller just
need to know a interface, in addition, the cgroup's configuration may be
different for
different OS platform, so it should looks like this:
def get_cgroup_mntpt(controller, cgconf="/etc/cgconfig.conf"):
controller_list = [ 'cpuacct', 'cpu', 'memory', 'cpuset', \
'devies', 'freezer', 'blkio', 'netcls' ]
f_cgcon = open("%s" %cgconf, "rU")
cgconf_txt = f_cgcon.read()
f_cgcon.close()
if controller not in controller_list:
raise error.TestError("Doesn't support controller <%s>" %
controller)
else:
mntpt = re.findall(r"(?<!#)%s\s*=\s*(.*);" %controller, cgconf_txt)
return mntpt[0]
