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.
