From 417a1a6d3d7abad4c5288135f640e6e38e7a65c5 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sun, 23 Sep 2007 13:19:55 +0900 Subject: [PATCH] ahci: move host flags over to pi.private_data Private pi.flags area is full and we need more private flags. Move host private flags over to pi.private_data. During initialization, these flags are copied to hpriv->flags.
