ATA_STD_PRERESET(9)		libata Library		   ATA_STD_PRERESET(9)

NAME
       ata_std_prereset - prepare for reset

SYNOPSIS
       int ata_std_prereset(struct ata_link * link, unsigned long deadline);

ARGUMENTS
       link
	   ATA link to be reset

       deadline
	   deadline jiffies for the operation

DESCRIPTION
       link is about to be reset. Initialize it. Failure from prereset makes
       libata abort whole reset sequence and give up that port, so prereset
       should be best-effort. It does its best to prepare for reset sequence
       but if things go wrong, it should just whine, not fail.

LOCKING
       Kernel thread context (may sleep)

RETURNS
       0 on success, -errno otherwise.
