From c429137a67b82788d24682153bb9c96501a9ef34 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 10 May 2010 21:41:38 +0200 Subject: libata-sff: port_task is SFF specific port_task is tightly bound to the standard SFF PIO HSM implementation. Using it for any other purpose would be error-prone and there's no such user and if some drivers need such feature, it would be much better off using its own. Move it inside CONFIG_ATA_SFF and rename it to sff_pio_task. The only function which is exposed to the core layer is ata_sff_flush_pio_task() which is renamed from ata_port_flush_task() and now also takes care of resetting hsm_task_state to HSM_ST_IDLE, which is possible as it's now specific to PIO HSM.
