The last cleanup introduced two harmless warnings:

fs/xfs/xfs_fsmap.c:480:1: warning: '__xfs_getfsmap_rtdev' defined but not used
fs/xfs/xfs_fsmap.c:372:1: warning: 'xfs_getfsmap_rtdev_rtbitmap_helper' defined but not used

This moves those two functions as well.

Fixes: bb9c2e543325 ("xfs: move more RT specific code under CONFIG_XFS_RT")

I don't reproduce the warning, but the patch looks fine:

Curious. I didn't get those warnings on gcc 6.4 or 7.2 on x86-64.

Oh, CONFIG_XFS_DEBUG=y hides them, because it removes the "static"
declaration from them. Ok, that makes sense - I almost never build
a non-debug kernel. Have to make sure when I do config changes next
time to build without debug...

Thanks, Arnd!

Cheers,

Dave.

Ah, that explains why I didn't reproduce them either, thanks!
