From f08dc1ac6b15c681f4643d8da1700e06c3855608 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 9 Dec 2010 15:59:32 +0100 Subject: [PATCH] libata: no special completion processing for EH commands ata_qc_complete() contains special handling for certain commands. For example, it schedules EH for device revalidation after certain configurations are changed. These shouldn't be applied to EH commands but they were. In most cases, it doesn't cause an actual problem because EH doesn't issue any command which would trigger special handling; however, ACPI can issue such commands via _GTF which can cause weird interactions. Restructure ata_qc_complete() such that EH commands are always passed on to __ata_qc_complete(). stable: Please apply to -stable only after 2.6.38 is released.
