Hello, I was wondering about the call to schedule in function qla4_82xx_crb_win_lock for driver drivers/scsi/qla4xxx/ql4_nx.c. It is called in 2 functions [qla4_82xx_rd_32 and qla4_82xx_wr_32] while holding a write_lock_irqsave. Normally we avoid using sleeping functions while holding a lock.
Is there some reason that I am overlooking? Why it is OK in this case? Are we using schedule() here intentionally? Thank you. -- Vaishali
