If anyone has any objections, please let me know. ------------------ From: Andrew Morton commit 9ad553abe66f8be3f4755e9fa0a6ba137ce76341 upstream. 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.
