I've discovered a bug in the PIDs cgroup. We aren't properly dealing
with css references (we grab a reference to a css in ->can_attach() and
then drop a reference to a *different* css in ->{cancel_,}attach(). This
is a quick patch I wrote which I believe fixes the problem by getting
cgroup_migrate() to grab a reference before ->can_attach() and once the
attach has failed or succeded.Aleksa Sarai (2): cgroup: get a ref to source csses when migrating cgroup: pids: fix invalid get/put usage kernel/cgroup.c | 21 +++++++++++++++++++-- kernel/cgroup_pids.c | 13 +------------ 2 files changed, 20 insertions(+), 14 deletions(-) -- 2.5.0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
