Subject: iomap: move struct iomap_page out of iomap.h
X-Git-Tag: v5.10.7~3671^2~21
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ab08b01ec0a205d9c98e712eb504c850a51e6fdb;p=platform%2Fkernel%2Flinux-rpi.git

iomap: move struct iomap_page out of iomap.h

Now that all the writepage code is in the iomap code there is no
need to keep this structure public.
