FROMLIST: android: binder: Drop lru lock in isolate callback
(from https://patchwork.kernel.org/patch/9945123/)
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.
Bug: 63926541
