Anton Ivanov	f88f0bdfc3	um: UBD Improvements ... UBD at present is extremely slow because it handles only one request at a time in the IO thread and IRQ handler. The single request at a time is replaced by handling multiple requests as well as necessary workarounds for short reads/writes. Resulting performance improvement in disk IO - 30% Signed-off-by: Anton Ivanov <aivanov@kot-begemot.co.uk> Signed-off-by: Richard Weinberger <richard@nod.at>	2016-12-14 22:46:55 +01:00
Richard Weinberger	91d44ff860	um: Cleanup SIGTERM handling ... Richard reported that some UML processes survive if the UML main process receives a SIGTERM. This issue was caused by a wrongly placed signal(SIGTERM, SIG_DFL) in init_new_thread_signals(). It disabled the UML exit handler accidently for some processes. The correct solution is to disable the fatal handler for all UML helper threads/processes. Such that last_ditch_exit() does not get called multiple times and all processes can exit due to SIGTERM.
