[PATCH] libata: pass qc around intead of ap during PIO The current code passes pointer to ap around and repeatedly performs ata_qc_from_tag() to access the ongoing qc. This is unnatural and makes EH synchronization cumbersome. Make PIO codes deal with qc instead of ap. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
