Series [01/19] block: add a bdev_check_media_change helper | expand

Commit Message

Christoph Hellwig Sept. 2, 2020, 2:12 p.m. UTC 
Switch to use bdev_check_media_change instead of check_disk_change and
call floppy_revalidate manually.  Given that floppy_revalidate only
deals with media change events, the extra call into ->revalidate_disk
from bdev_disk_changed is not required either, so stop wiring up the
method.
