Vikram Mulukutla 2bbf3a762a Revert "ANDROID: sched/tune: Initialize raw_spin_lock in boosted_groups" ... This reverts commit c5616f2f874faa20b59b116177b99bf3948586df. If we re-init the per-cpu boostgroup spinlock every time that we add a new boosted cgroup, we can easily wipe out (reinit) a spinlock struct while in a critical section. We should only be setting up the per-cpu boostgroup data, and the spin_lock initialization need only happen once - which we're already doing in a postcore_initcall. For example: -------- CPU 0 -------- | -------- CPU1 -------- cgroupX boost group added | schedtune_enqueue_task | acquires(bg->lock) | cgroupY boost group added | for_each_cpu() | raw_spin_lock_init(bg->lock) releases(bg->lock) | BUG (already unlocked) | | This results in the following BUG from the debug spinlock code: BUG: spinlock already unlocked on CPU#5, rcuop/6/68 CRs-fixed: 2113062 Change-Id: I1cd780d9ba5801cf99bfe46504b18a88e45f17a8 Signed-off-by: Vikram Mulukutla <markivx@codeaurora.org>		2017-09-22 04:24:28 -07:00
