ata_std_prereset - prepare for reset
2. SYNOPSIS ▲
int ata_std_prereset(struct ata_link * link , unsigned long deadline );
3. ARGUMENTS ▲
ATA link to be reset
deadline jiffies for the operation
4. 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.
5. LOCKING ▲
Kernel thread context (may sleep)
6. RETURNS ▲
0 on success, -errno otherwise.
