    Subject[PATCH 5.5 170/176] locking/lockdep: Fix lockdep_stats indentation problem
    Date
    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")
