SCSI sg: Questions regarding jiffies usage

[Adrian Bunk <bunk@fs.tum.de>]

Hi,

I have some questions regarding jiffies usage in the SCSI sg driver in 
2.6.7-mm7:


Is there a good reason for the local sg_ms_to_jif/sg_jif_to_ms functions  
instead of using the time.h msecs_to_jiffies/jiffies_to_msecs macros?

In function sg_new_write:
   timeout = sg_ms_to_jif(srp->header.timeout);
How is it possible that srp->header.timeout isn't already
in jiffies?

Why do both sg_add_request and sg_common_write set
  duration = jiffies
?


TIA
Adrian
