commit 6b2daec19094a90435abe67d16fb43b1a5527254 upstream.
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 Signed-off-by: Greg Kroah-Hartman gregkh@linuxfoundation.org
