Subject: vfs: rename clone_verify_area to remap_verify_area
X-Git-Tag: v4.20-rc1~23^2~20
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=6095028b455d775e369ae27875f698ff0f6fdeb8;p=thirdparty%2Fkernel%2Flinux.git

vfs: rename clone_verify_area to remap_verify_area

Since we use clone_verify_area for both clone and dedupe range checks,
rename the function to make it clear that it's for both.
