Subject: [PATCH 0/3] may_power_off for scsi device
Date: Thu, 30 Aug 2012 14:43:57 +0800	[thread overview]
Message-ID: <1346309040-27112-1-git-send-email-aaron.lu@intel.com> (raw)

Add a new flag may_power_off for scsi device to let user control when
it is runtime suspended, can we remove its power.

This patchset makes the following patch sent previously deprecated:
[PATCH] scsi: sr: add may_power_off flag
http://marc.info/?l=linux-scsi&m=134614323832520&w=2

The patch "scsi: pm: add may_power_off flag" also appears in another
patchset intended for libata due to libata will use this flag to
decide if ACPI D3cold can be used. They two patches are identical.

Based on top of the previously sent v4 ZPODD patchset:
