fix compat handling of FICLONERANGE, FIDEDUPERANGE and FS_IOC_FIEMAP
Unlike FICLONE, all of those take a pointer argument; they do need compat_ptr() applied to arg. Fixes: d79bdd52d8be ("vfs: wire up compat ioctl for CLONE/CLONE_RANGE") Fixes: 54dbc1517237 ("vfs: hoist the btrfs deduplication ioctl to the vfs") Fixes: ceac204e1da9 ("fs: make fiemap work from compat_ioctl") Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
