Subject: elevator: use ELV_NAME_MAX instead of magic number 16 for chosen_elevator
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=484fc254b88257a2d8b3759aa062e8e8b35e0988;p=linux.git

elevator: use ELV_NAME_MAX instead of magic number 16 for chosen_elevator

We have ELV_NAME_MAX defined to 16, and hence we should use it
instead of the magic nubmer 16 for elevator's name string.
