| Subject: UBIFS: fix debugging messages |
| |
| From: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> |
| |
| commit d34315da9146253351146140ea4b277193ee5e5f upstream. |
| |
| Patch 56e46742e846e4de167dde0e1e1071ace1c882a5 broke UBIFS debugging messages: |
| before that commit when UBIFS debugging was enabled, users saw few useful |
| debugging messages after mount. However, that patch turned 'dbg_msg()' into |
| 'pr_debug()', so to enable the debugging messages users have to enable them |
| first via /sys/kernel/debug/dynamic_debug/control, which is very impractical. |
| |
| This commit makes 'dbg_msg()' to use 'printk()' instead of 'pr_debug()', just |
| as it was before the breakage. |
