| Subject: locking/lockdep: Fix lockdep_stats indentation problem |
| |
| From: Waiman Long <longman@redhat.com> |
| |
| commit a030f9767da1a6bbcec840fc54770eb11c2414b6 upstream. |
| |
| It was found that two lines in the output of /proc/lockdep_stats have |
| indentation problem: |
| |
| # cat /proc/lockdep_stats |
| : |
| in-process chains: 25057 |
| stack-trace entries: 137827 [max: 524288] |
| number of stack traces: 7973 |
| number of stack hash chains: 6355 |
| combined max dependencies: 1356414598 |
| hardirq-safe locks: 57 |
| hardirq-unsafe locks: 1286 |
| : |
| |
| All the numbers displayed in /proc/lockdep_stats except the two stack |
| trace numbers are formatted with a field with of 11. To properly align |
| all the numbers, a field width of 11 is now added to the two stack |
| trace numbers. |
| |
| Fixes: 8c779229d0f4 ("locking/lockdep: Report more stack trace statistics") |
