Subject: Adaptec DPT call schedule_timeout with irq off
Date: Fri, 26 Aug 2005 17:45:28 -0700	[thread overview]
Message-ID: <430FB7A8.8020105@mvista.com> (raw)

I noticed that in the Adaptec DPT driver, drivers/scsi/dpt_i2o.c in 
funciton adapt_i2o_post_wait() around line 1161ish. spin_lock_irqsave() 
is called. However then spin_unlock() is called 2 lines later and 
leaving IRQ disabled. Then a little bit later, schedule_timeout() is 
called with IRQ off. Isn't that bad? Why was irq left off earlier 
instead of doing spin_unlock_irqrestore()? Am I missing something.....

Please cc me on replies. Thank you!
