[PATCH] UDF write support problem in 2.5.7

 From Peter Osterlund <petero2@telia.com>

I can't get UDF write support to work in kernel 2.5.7 or 2.5.7-pre2.
The problem is that linux/config.h is not included, so CONFIG_UDF_RW
is undefined and the driver is compiled without write support. This
patch fixes my problem:

include/linux/udf_fs.h
