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)

RETURN
       0 on success, -errno otherwise.
