locking/lockdep: Fix lockdep_stats indentation problem
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")
