Add to man page: 0 as prio when -i, -b

As we know the batch and idle algorithms don't have priorities. But chrt expects '0' as the priority, otherwise the command fails.

# chrt -i cat /etc/fstab

chrt - manipulate real-time attributes of a process

Set policy:
chrt [options] [<policy>] <priority> [-p <pid> | <command> [<arg>...]]
...
...
...

# chrt -i 0 cat /etc/fstab
# /etc/fstab: static file system information.
#
# noatime turns off atimes for increased performance (atimes normally aren't
...
...
...

Added, thanks.
