[PATCH] libata: clear ap->active_tag atomically w.r.t. command completion ap->active_tag was cleared in ata_qc_free(). This left ap->active_tag dangling after ata_qc_complete(). Spurious interrupts inbetween could incorrectly access the qc. Clear active_tag in ata_qc_complete(). This change is necessary for later EH changes. Signed-off-by: Tejun Heo <htejun@gmail.com>
