* xen: remove DEFINE_XENBUS_DRIVER() macroDavid Vrabel2014-10-061-3/+5
| | | | | | | | | | The DEFINE_XENBUS_DRIVER() macro looks a bit weird and causes sparse errors. Replace the uses with standard structure definitions instead. This is similar to pci and usb device registration. Signed-off-by: David Vrabel <david.vrabel@citrix.com>
* xenbus: convert bus code to use dev_groupsGreg Kroah-Hartman2013-10-161-1/+1
| | | | | | | | | | | | The dev_attrs field of struct bus_type is going away soon, dev_groups should be used instead. This converts the xenbus code to use the correct field.

* xen: Convert printks to pr_<level>Joe Perches2013-06-281-3/+5
| | | | | | | | | | | | | | | | | Convert printks to pr_<level> (excludes printk(KERN_DEBUG...) to be more consistent throughout the xen subsystem. Add pr_fmt with KBUILD_MODNAME or "xen:" KBUILD_MODNAME Coalesce formats and add missing word spaces Add missing newlines Align arguments and reflow to 80 columns Remove DRV_NAME from formats as pr_fmt adds the same content This does change some of the prefixes of these messages but it also does make them more consistent.

* Xen: consolidate and simplify struct xenbus_driver instantiationJan Beulich2012-01-041-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | The 'name', 'owner', and 'mod_name' members are redundant with the identically named fields in the 'driver' sub-structure. Rather than switching each instance to specify these fields explicitly, introduce a macro to simplify this. Eliminate further redundancy by allowing the drvname argument to DEFINE_XENBUS_DRIVER() to be blank (in which case the first entry from the ID table will be used for .driver.name). Also eliminate the questionable xenbus_register_{back,front}end() wrappers - their sole remaining purpose was the checking of the 'owner' field, proper setting of which shouldn't be an issue anymore when the macro gets used. v2: Restore DRV_NAME for the driver name in xen-pciback.

* xen: Add export.h for THIS_MODULE/EXPORT_SYMBOL to various xen users.Paul Gortmaker2011-10-311-0/+1
| | | | | | | | Things like THIS_MODULE and EXPORT_SYMBOL were simply everywhere because module.h was also everywhere. But we are fixing the latter. So we need to call out the real users in advance. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* xen/xenbus: Remove the unnecessary check.Konrad Rzeszutek Wilk2011-10-191-2/+0
| | | | | | | | | .. we check whether 'xdev' is NULL - but there is no need for it as the 'dev' check is done before. The 'dev' is embedded in the 'xdev' so having xdev != NULL with dev being being checked is not going to happen. Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
* xen: Add module alias to autoload backend driversBastian Blank2011-06-301-0/+3
| | | | | | | | | | All the Xen backend drivers are assigned to a special bus type xen-backend. This patch exports xen-backend:* names through modalias and uevent to autoload them.

* xen: Populate xenbus device attributesBastian Blank2011-06-301-5/+1
| | | | | | | | | | | | The xenbus bus type uses device_create_file to assign all used device attributes. However it does not remove them when the device goes away. This patch uses the dev_attrs field of the bus type to specify default attributes for all devices.
