This does not match the behaviour of the bay\ndriver, and may result in confusion when two hotplug requests are\nreceived for the same device. This patch limits the hotplug notification\nto removable ACPI devices, which in turn allows it to use the _STA\nmethod to determine whether the device has been removed or inserted.\nOn removal, devices are marked as detached. On insertion, a hotplug scan\nis started. This should avoid lockups caused by the ata layer attempting\nto scan devices which have been removed. The uevent sending is moved\noutside the spinlock in order to avoid a warning generated by it firing\nwhen interrupts are disabled.\n\nSigned-off-by: Matthew Garrett \u003cmjg@redhat.com\u003e\nSigned-off-by: Jeff Garzik \u003cjgarzik@redhat.com\u003e\n"

These two\nfunctions are responsible for determining whether specific ACPI method\nis used and when.\n\nOn resume, _GTF is scheduled by setting ATA_DFLAG_ACPI_PENDING device\nflag.  This is done this way to avoid performing the action on wrong\ndevice device (device swapping while suspended).\n\nOn every ata_dev_configure(), ata_acpi_on_devcfg() is called, which\nperforms _SDD and _GTF.  _GTF is performed only after resuming and, if\nSATA, hardreset as the ACPI spec specifies.  As _GTF may contain\narbitrary commands, IDENTIFY page is re-read after _GTF taskfiles are\nexecuted.\n\nIf one of ACPI methods fails, ata_acpi_on_devcfg() retries on the\nfirst failure.  If it fails again on the second try, ACPI is disabled\non the device.  Note that successful configuration clears ACPI failed\nstatus.\n\nWith all feature checks moved to the above two functions,\ndo_drive_set_taskfiles() is trivial and thus collapsed into\nata_acpi_exec_tfs(), which is now static and converted to return the\nnumber of executed taskfiles to be used by ata_acpi_on_resume().  As\nfailures are handled properly, ata_acpi_push_id() now returns -errno\non errors instead of unconditional zero.\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\nSigned-off-by: Jeff Garzik \u003cjeff@garzik.org\u003e\n"
