jun Heo 1291906772 +0100 committer Jeff Garzik 1293215658 -0500 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.
