Hello !
While polling the contents of a cgroup task file, I caught the
following corruption. Is there a known race (and a fix) or should
I start digging ?
the program running in the cgroup is fork/exec intensive:
while (1) {
int i, s;
for (i = 0; i < count; i++)
reproduce it.
I did reproduce it on a FC5 desktop finally.
get_user_ns() returns NULL when CONFIG_USER_NS=n and this breaks
sigio_perm() which does not expect NULL values for ->user_ns.
I would fix this with the following patch.

When a namespace is unshared, a refcount on the previous nsproxy is
