From 52b329d678e8495bda4d943df6444403f41c57ff Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Tue, 10 Apr 2018 16:34:41 -0700 Subject: [PATCH] fs/reiserfs/journal.c: add missing resierfs_warning() arg 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.
