From: Andrew Morton Date: Tue, 10 Apr 2018 23:34:41 +0000 (-0700) Subject: fs/reiserfs/journal.c: add missing resierfs_warning() arg X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f659e7e79f52657b88ea0f9ed473fe0958d31996;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git 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.
