Hi, Tejun, Kame, This series is composed of the two patches of the last fix, with no changes (only exception is the removal of x = false assignments that Tejun requested, that is done now). Note also that patch 1 of this series was reused by me in the slab accounting patches for memcg. The first patch, that adds a mutex to memcg is dropped. I didn't posted it before so I could wait for Kame to get back from his vacations and properly review it. Kame: Steven Rostedt pointed out that our analysis of the static branch updates were wrong, so the mutex is really not needed. The key to understand that, is that atomic_inc_not_zero will only return right away if the value is not yet zero - as the name implies - but the update in the atomic variable only happens after the code is patched. Therefore, if two callers enters with a key value of zero, both will be held at the jump_label_lock() call, effectively guaranteeing the behavior we need.
