[ Upstream commit 16203e9cd01896b4244100a8e3fb9f6e612ab2b1 ]
Without this we were not getting the thousands separator for big numbers.
Noticed while developing 'perf bench uprobe', but the use of %' predates that, for instance 'perf bench syscall' uses it.
Before:
# perf bench uprobe all # Running uprobe/baseline benchmark... # Executed 1000 usleep(1000) calls Total time: 1054082243ns
1054082.243000 nsecs/op
#
After:
# perf bench uprobe all # Running uprobe/baseline benchmark... # Executed 1,000 usleep(1000) calls Total time: 1,053,715,144ns
1,053,715.144000 nsecs/op
#
