SubjectRe: Linux 2.4.10-pre6: necessary patches
Most are old ones, from way back 2.4.9 to latest -pre5.

drivers/block/genhd.c needs a few EXPORT_SYMBOLs. A peek at the -ac
series shows an added lock:

static rwlock_t gendisk_lock;

which is used by all the functions. It may be necessary now
that these functions are used from so many places.--- linux/drivers/block/genhd.c.orig Sun Sep 9 18:54:21 2001
