+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 checking the MS_SILENT flag in ubifs_read_sb_node and
-passing it down to ubifs_read_node, which now got an additional
-parameter for that purpose.
+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.
