*Calling of sd_prep_fn*
?
Is this request queue sdp->request_queue, different from the request queue,
for which scsi_prep_fn is used??
Are they on different layers ?
Is there some relation between them ?
Thanks

Hi All
i have got a requirement where I need to encrypt/decrypt data that goes
from scsi layer to a particular block device.
As per my understanding till now on scsi subsystem in linux, i think i need
to
use crypto api and call appropriate encrypt/decrypt function from sd driver
for block device.
e->get_sb(type, flags, name, data,
mnt);>>>>>>>>>>>>>>>>thats the line i want to catch, in assembly above.
Where is this call made in assembly ???*
if (error < 0)
goto out_free_secdata;
BUG_ON(!mnt->mnt_sb);

Hi all,
I have an smp linux redhat kernel running on many cpu cores.
I know that one process running on one of cpu has tried for Big kernel lock
.
I am finding that another process on another CPU is trying for BKL.
My question is :-
