Bug#731715: cgroup-bin: can't add process PID to group/tasks

[itsme <mymail@ishere.ru>]

any ideas?

root@debian-server:/sys/fs/cgroup/test# echo $$
3173
root@debian-server:/sys/fs/cgroup/test# echo $$ > tasks
bash: echo: write error: No space left on device

...

root@debian-server:/sys/fs/cgroup/test# cat cpuset.cpus

root@debian-server:/sys/fs/cgroup/test# cat cpuset.mems

root@debian-server:/sys/fs/cgroup/test# cat ../cpuset.cpus
0-1
root@debian-server:/sys/fs/cgroup/test# cat ../cpuset.mems
0

Hmmm...

root@debian-server:/sys/fs/cgroup/test# cat ../cpuset.cpus > cpuset.cpus
root@debian-server:/sys/fs/cgroup/test# cat ../cpuset.mems > cpuset.mems
root@debian-server:/sys/fs/cgroup/test# echo $$ > tasks
root@debian-server:/sys/fs/cgroup/test# cat tasks
3173

Only if these two values ​​are empty.
