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.
