[PATCH 05/24] block: remove the update_bdev parameter from set_capacity_revalidate_and_notify

Christoph Hellwig
2020-11-06T19:04:08Z

The update_bdev argument is always set to true, so remove it. Also
rename the function to the slighly less verbose set_capacity_and_notify,
as propagating the disk size to the block device isn't really
revalidation.
