Subject: [PATCH -next] fs: fix compat_ioctl when CONFIG_BLOCK=n

From: Randy Dunlap <randy.dunlap@...cle.com>

fs/compat_ioctl.c should omit pktcdvd.h and its ioctl when CONFIG_BLOCK
is not enabled.  This fixes these build errors:

In file included from fs/compat_ioctl.c:105:
include/linux/pktcdvd.h:166: error: field 'read_queue' has incomplete type
include/linux/pktcdvd.h:167: error: field 'write_queue' has incomplete type
include/linux/pktcdvd.h:207: error: field 'orig_bios' has incomplete type
make[2]: *** [fs/compat_ioctl.o] Error 1
