   Too many commas. :-)


from bdev_disk_changed is not required either, so stop wiring up the
method.

[PATCH 16/19] sd: use bdev_check_media_change

2020-09-08 Thread Christoph Hellwig 
Switch to use bdev_check_media_change instead of check_disk_change and
call sd_revalidate_disk manually.  As sd also calls sd_revalidate_disk
manually during probe and open, , the extra call into ->revalidate_disk
from bdev_disk_changed is not required either, so stop wiring up the
method.
