From 90bea5a3f0bf680b87b90516f3c231997f4b8f3b Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Mon, 2 Jun 2014 15:51:10 +0200 Subject: UBIFS: respect MS_SILENT mount flag When attempting to mount a non-ubifs formatted volume, lots of error messages (including a stack dump) are thrown to the kernel log even if the MS_SILENT mount flag is set. Fix this by introducing adding an additional state-variable in struct ubifs_info and suppress error messages in ubifs_read_node if MS_SILENT is set.
