Subject[PATCH 4/6] perf lock: Fix lock name length check for printing
Date
It has 20 character spaces for name so lock names shorter than 20
should be printed without ellipsis.

Before:
# perf lock report
Name acquired contended avg wait (ns) total wait (ns) max wait (ns) min wait (ns)

rcu_read_lock 251225 0 0 0 0 0
&(ei->i_block_re... 8731 0 0 0 0 0
&sb->s_type->i_l... 8731 0 0 0 0 0
hrtimer_bases.lo... 5261 0 0 0 0 0
hrtimer_bases.lo... 2626 0 0 0 0 0
hrtimer_bases.lo... 1953 0 0 0 0 0
hrtimer_bases.lo... 1382 0 0 0 0 0
cpu_hotplug_lock... 1350 0 0 0 0 0

After:
# perf lock report
Name acquired contended avg wait (ns) total wait (ns) max wait (ns) min wait (ns)

rcu_read_lock 251225 0 0 0 0 0
&(ei->i_block_re... 8731 0 0 0 0 0
&sb->s_type->i_l... 8731 0 0 0 0 0

hrtimer_bases.lock 1382 0 0 0 0 0
cpu_hotplug_lock 1350 0 0 0 0 0
