  "message": "cgroups: change css_set freeing mechanism to be under RCU\n\nChanges css_set freeing mechanism to be under RCU\n\nThis is a prepatch for making the procs file writable. In order to free the\nold css_sets for each task to be moved as they\u0027re being moved, the freeing\nmechanism must be RCU-protected, or else we would have to have a call to\nsynchronize_rcu() for each task before freeing its old css_set.\n\nSigned-off-by: Ben Blum \u003cbblum@google.com\u003e\nSigned-off-by: Paul Menage \u003cmenage@google.com\u003e\nCc: \"Paul E.
