[PATCH 4/5] block: remove the gendisk argument to blk_execute_rq
Christoph Hellwig
hch at lst.de
Mon Sep 27 22:22:10 PDT 2021
Remove the gendisk aregument to blk_execute_rq and blk_execute_rq_nowait
given that it is unused now. Also convert the boolean at_head parameter
to actually use the bool type while touching the prototype.
