Unlinking death recipients (from linkToDeath) is a normal part of Binder operation, and doing it when a BpBinder's refcount has reached 0 is not much different. This log message is constantly spamming when swiping as part of a back navigation gesture: 04-05 22:29:41.402 655 3888 I BpBinder: onLastStrongRef automatically unlinking death recipients: <uncached descriptor> 04-05 22:29:41.413 655 3888 I BpBinder: onLastStrongRef automatically unlinking death recipients: <uncached descriptor> 04-05 22:29:41.424 655 3888 I BpBinder: onLastStrongRef automatically unlinking death recipients: <uncached descriptor> 04-05 22:29:41.435 655 681 I BpBinder: onLastStrongRef automatically unlinking death recipients: <uncached descriptor> 04-05 22:29:41.447 655 3888 I BpBinder: onLastStrongRef automatically unlinking death recipients: <uncached descriptor> Logging is relatively expensive on Android and the log spam isn't useful, so suppress this log message by setting it to the verbose log level.

When `listenerStatsToSend` in `TransactionCallbackInvoker::sendCallbacks` is empty, simply return to avoid the redundant thread scheduling overhead caused by `BackgroundExecutor::getInstance()`. Change-Id: I00a717933406b2580e5d28daca28e94f0b80f9c8 Signed-off-by: Liangliang Sui <[email protected]>

The epoll_pwait2 syscall was introduced in Linux 5.11. Older kernels return ENOSYS when attempting to use this syscall, causing buffer release operations to fail. 12-07 18:05:15.668 2095 2226 E BLASTBufferQueue: epoll_wait error while waiting for buffer release. errno=38 message='Function not implemented' 12-07 18:05:15.668 2095 2226 E BLASTBufferQueue: epoll_wait error while waiting for buffer release. errno=38 message='Function not implemented' Test: Boot device with kernel < 5.11, verify no epoll errors Signed-off-by: Dmitrii <[email protected]>
