* [SCSI] enclosure: fix oops while iterating enclosure_status arrayJames Bottomley2009-12-101-0/+2
| | | | | | | | | | | | | | | Based on patch originally by Jeff Mahoney <jeffm@suse.com> enclosure_status is expected to be a NULL terminated array of strings but isn't actually NULL terminated. When writing an invalid value to /sys/class/enclosure/.../.../status, it goes off the end of the array and Oopses. Fix by making the assumption true and adding NULL at the end.

* [SCSI] ses: add support for enclosure component hot removalJames Bottomley2009-08-221-1/+1
| | | | | | | | | | | | Right at the moment, hot removal of a device within an enclosure does nothing (because the intf_remove only copes with enclosure removal not with component removal). Fix this by adding a function to remove the component. Also needed to fix the prototype of enclosure_remove_device, since we know the device we've removed but not the internal component number Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
* [SCSI] ses: fix hotplug with multiple devices and expandersJames Bottomley2009-08-221-1/+2
| | | | | | | | | | | | In a situation either with expanders or with multiple enclosure devices, hot add doesn't always work. This is because we try to find a single enclosure device attached to the host. Fix this by looping over all enclosure devices attached to the host and also by making the find loop recognise that the enclosure devices may be expander remote (i.e. not parented by the host).

| | | | | | | | | | | | | It's big, but there doesn't seem to be a way to split it up smaller...

* [SCSI] enclosure: add support for enclosure servicesJames Bottomley2008-02-071-0/+129
The enclosure misc device is really just a library providing sysfs support for physical enclosure devices and their components. Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
