NAME
ata_std_prereset - prepare for resetSYNOPSIS
- 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.
