[PATCH 5.10 056/133] block: remove the update_bdev parameter to set_capacity_revalidate_and_notify

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

5.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Christoph Hellwig <hch@lst.de>

[ Upstream commit 449f4ec9892ebc2f37a7eae6d97db2cf7c65e09a ]

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.
