perf hists: Print newline between hists callchains
Tiny cosmetic fix. The lack of a newline between hists callchains was
looking slightly messy.
Before:
0.24% swapper [kernel.kallsyms] [k] _raw_spin_lock_irq
|
--- _raw_spin_lock_irq
run_timer_softirq
__do_softirq
call_softirq
do_softirq
irq_exit
smp_apic_timer_interrupt
apic_timer_interrupt
default_idle
amd_e400_idle
cpu_idle
start_secondary
0.10% perf [kernel.kallsyms] [k] lock_is_held
|
--- lock_is_held
__might_sleep
mutex_lock_nested
perf_event_for_each_child
perf_ioctl
do_vfs_ioctl
sys_ioctl
system_call_fastpath
ioctl
cmd_record
run_builtin
