Sherry Yang a1b2289cef android: binder: drop lru lock in isolate callback ... Drop the global lru lock in isolate callback before calling zap_page_range which calls cond_resched, and re-acquire the global lru lock before returning. Also change return code to LRU_REMOVED_RETRY. Use mmput_async when fail to acquire mmap sem in an atomic context. Fix "BUG: sleeping function called from invalid context" errors when CONFIG_DEBUG_ATOMIC_SLEEP is enabled. Also restore mmput_async, which was initially introduced in commit ec8d7c14ea ("mm, oom_reaper: do not mmput synchronously from the oom reaper context"), and was removed in commit 2129258024 ("mm: oom: let oom_reap_task and exit_mmap run concurrently").
