[PATCH] Fix units/partition count in sd.c
Symptom:
When a scsi disk is removed other scsi disk with biggest minor #
disapears in /proc/partition at the same time.
Cause and fix:
sd.c decreases nr_real on disk removal but because nr_real is not
real # of devices but max # of devices of a major #,
it doesn't need to be changed on disk add/remove.
2.6 has little different structure but it does like this
sd.c:sd_probe()
gd->minors = 16;
sd.c | 4 +---
