Subject: scsi_track_queue_full function - static values ?
Date: Tue, 07 Mar 2006 14:32:44 +0100	[thread overview]
Message-ID: <440D8B7C.9020001@ext.bull.net> (raw)

Hi,


I was looking at the scsi_track_queue_full (driver/scsi/scsi.c) function.

Can someone tell me how have been defined all the static values in this function ?

- we may have (max) 16 (>>4) jiffies between calls (else there's no need to call 
this function...),

- queue_full_depth_count should be > 10 (else queue depth still not changed),

- if lun queue depth < 8, lun queue depth is set with cmd_per_lun
(what's happen if cmd_per_lun > 8 ???)


May someone add some #define for these values ?
Is it a way to use 'auto-adapted' values ?

Best regards.
