From 2a40024127ef9af9c2633f07da93542ec570d181 Mon Sep 17 00:00:00 2001 From: Basil Gello Date: Tue, 18 Jul 2017 22:00:01 +0300 Subject: [PATCH] secril-client: close fds on I/O errors if a kernel device returns an I/O error, it is better not to chew the CPU resources retrying I/O operation on a not ready device. Fixes periodical 100%-core load in audioserver after a voice call completion.
