Subject: virtio-blk: remove a spurious call to revalidate_disk_size
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ddff331a14eb7d5af08e63579ba28c289db26e20;p=linux.git

virtio-blk: remove a spurious call to revalidate_disk_size

revalidate_disk_size just updates the block device size from the disk
size.  Thus calling it from virtblk_update_cache_mode doesn't actually
do anything.
