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.
