Subject: block: always use 'e' when printing scheduler name
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7a3b3660fd30c028e7ae1cd82697933789962406;p=linux.git

block: always use 'e' when printing scheduler name

Printing e->elevator_name in all cases improves the readability, and
'e' and 'cur' are identical in this branch.
