Subject: sd: open code revalidate_disk
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=033a1b98b1f8a823fb0bd985d45290016eee54ce;p=linux.git

sd: open code revalidate_disk

Instead of calling revalidate_disk just do the work directly by
calling sd_revalidate_disk, and revalidate_disk_size where needed.
