Itai,
After applying your patch to 2.4.18, I see the following
problems:
1. ide-scsi does NOT work. /proc/scsi/scsi shows NO
devices and /proc/scsi/ide-scsi is empty.
2. /proc/scsi/{scsi, ide-scsi, scsi_test} are all empty!
3. After ``rmmod scsi_test'' and ``ls /proc/scsi''
the kernel OOPS-es.
NONE of those problems exist with a non-patched kernel.
I used kernel 2.4.18, but doubt there'd difference for
2.5.x since the host_no stuff hasn't changed (2.5.22).
I've attached the OOPS and the tgz of my testing
module scsi_test.o.
Interested parties: this is in regards to the
scsi subsystem assigning _repeating_ host numbers
to hosts registered! See my message
``/proc/scsi/driver/hosts with same numeric???''
dated 2002/05/29 on linux-scsi ML.
To repeat the problem:
$ insmod scsi_reg.o
$ rmmod scsi_reg
$ insmod scsi_req.o MaxHosts=20
$ ls /proc/scsi/scsi_test
Voila!
Here is the OOPS:
