[PATCH] Btrfs-progs: fix the min ticks check in print_seek_histogram

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Before I had been dividing by 5 but that gave me too much output so I changed it
to 20 without changing the min seeks test.  Fix this to avoid a divide by 0
problem.  Thanks,
