Hi,

I sniff tested 2K lun support with 2.6.12-rc6-mm1 on
my AMD64 box. I had to tweak qlogic driver and
scsi_scan.c to see all the luns.

(2.6.12-rc6 doesn't see all the LUNS due to max_lun
issue - which is fixed in scsi-git tree).

Test 1:
run dds on all 2048 "raw" devices - worked
great. No issues.

Tests 2:
run "dds" on 2048 filesystems (one file
per filesystem). Kind of works. I was expecting better
responsiveness & stability.

Overall - Good news is, it works.

Not so good news - with filesystem tests, machine becomes
unresponsive, lots of page allocation failures but machine
stays up and completes the tests and recovers.

Thanks,
Badari
