Subject: fs/reiserfs/journal.c: add missing resierfs_warning() arg
One use of the reiserfs_warning() macro in journal_init_dev() is missing a
parameter, causing the following warning:
REISERFS warning (device loop0): journal_init_dev: Cannot open '%s': %i journal_init_dev:
This also causes a WARN_ONCE() warning in the vsprintf code, and then a
panic if panic_on_warn is set.
Please remove unsupported %/ in format string
WARNING: CPU: 1 PID: 4480 at lib/vsprintf.c:2138 format_decode+0x77f/0x830 lib/vsprintf.c:2138
Kernel panic - not syncing: panic_on_warn set ...
Just add another string argument to the macro invocation.
