[PATCH blktests 03/14] common: Move set_scheduler() function from multipath-over-rdma to rc

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

 



From: Shin'ichiro Kawasaki <shinichiro.kawasaki@xxxxxxx>

set_scheduler() function defined in common/multipath-over-rdma is useful
to set up specific IO scheduler not only for multipath tests but also for
zoned block device tests. Move the function to common/rc to reuse it for
test groups other than multipath.
