351What: fakephp and associated sysfs files in /sys/bus/pci/slots/
352When: 2011
353Why: In 2.6.27, the semantics of /sys/bus/pci/slots was redefined to
354 represent a machine's physical PCI slots. The change in semantics
355 had userspace implications, as the hotplug core no longer allowed
356 drivers to create multiple sysfs files per physical slot (required
357 for multi-function devices, e.g.). fakephp was seen as a developer's
358 tool only, and its interface changed. Too late, we learned that
359 there were some users of the fakephp interface.
360
361 In 2.6.30, the original fakephp interface was restored. At the same
362 time, the PCI core gained the ability that fakephp provided, namely
363 function-level hot-remove and hot-add.
364
365 Since the PCI core now provides the same functionality, exposed in:
366
367 /sys/bus/pci/rescan
368 /sys/bus/pci/devices/.../remove
369 /sys/bus/pci/devices/.../rescan
370
371 there is no functional reason to maintain fakephp as well.
372
373 We will keep the existing module so that 'modprobe fakephp' will
374 present the old /sys/bus/pci/slots/... interface for compatibility,
375 but users are urged to migrate their applications to the API above.
376
377 After a reasonable transition period, we will remove the legacy
378 fakephp interface.
