Alan Stern suggested that I should not mess runtime suspend with runtime power off, but the current zpodd implementation made it not easy to seperate. So I re-wrote the zpodd implementation, the end result is, normal ODD can also enter runtime suspended state, but their power won't be removed. v4: Rebase on top of Linus' tree, due to this, the problem of a missing flag in v3 is gone; Add a new function scsi_autopm_put_device_autosuspend to first mark last busy for the device and then put autosuspend it as suggested by Oliver Neukum. Typo fix as pointed by Sergei Shtylyov. Check can_power_off flag before any runtime pm operations in sr. v3: Rebase on top of scsi-misc tree; Add the sr related patches previously in Jeff's libata tree; Re-organize the sr patches. A problem for now: for patch scsi: sr: support zero power ODD(ZPODD) I can't set a flag in libata-acpi.c since a related function is missing in scsi-misc tree. Will fix this when 3.6-rc1 released. v2: Bug fix for v1; Use scsi_autopm_* in sr driver instead of pm_runtime_*; v1: Here are some patches to make ZPODD easier to use for end users and a fix for using ZPODD with system suspend. Aaron Lu (7): scsi: sr: support runtime pm for ODD block: genhd: export disk_(un)block_events scsi: sr: block events checking when suspended for zpodd libata: acpi: set can_power_off for both ODD and HD scsi: pm: add may_power_off flag scsi: sr: use may_power_off libata: acpi: respect may_power_off flag block/genhd.c | 2 ++ drivers/ata/libata-acpi.c | 35 +++++++++++++------ drivers/scsi/scsi_sysfs.c | 10 +++--- drivers/scsi/sr.c | 85 ++++++++++++++++++++++++++++++++++++++++++++++ drivers/scsi/sr.h | 1 + include/scsi/scsi_device.h | 2 ++ 6 files changed, 120 insertions(+), 15 deletions(-) -- 1.7.11.5
