258 | What: GPIO autorequest on gpio_direction_{input,output}() in gpiolib | ||
259 | When: February 2010 | ||
260 | Why: All callers should use explicit gpio_request()/gpio_free(). | ||
261 | The autorequest mechanism in gpiolib was provided mostly as a | ||
262 | migration aid for legacy GPIO interfaces (for SOC based GPIOs). | ||
263 | Those users have now largely migrated. Platforms implementing | ||
264 | the GPIO interfaces without using gpiolib will see no changes. | ||

319 | When: 2.6.31 | ||
320 | Why: Non root users need to be part of /proc/sys/vm/hugetlb_shm_group or | ||
321 | have CAP_IPC_LOCK to be able to allocate shm segments backed by | ||
322 | huge pages. The mlock based rlimit check to allow shm hugetlb is | ||

401 | What: fakephp and associated sysfs files in /sys/bus/pci/slots/ | ||
402 | When: 2011 | ||
403 | Why: In 2.6.27, the semantics of /sys/bus/pci/slots was redefined to | ||
404 | represent a machine's physical PCI slots. The change in semantics | ||
405 | had userspace implications, as the hotplug core no longer allowed | ||
406 | drivers to create multiple sysfs files per physical slot (required | ||
407 | for multi-function devices, e.g.). fakephp was seen as a developer's | ||
408 | tool only, and its interface changed. Too late, we learned that | ||
409 | there were some users of the fakephp interface. | ||
410 | |||
411 | In 2.6.30, the original fakephp interface was restored. At the same | ||
412 | time, the PCI core gained the ability that fakephp provided, namely | ||
413 | function-level hot-remove and hot-add. | ||
414 | |||
415 | Since the PCI core now provides the same functionality, exposed in: | ||
416 | |||
417 | /sys/bus/pci/rescan | ||
418 | /sys/bus/pci/devices/.../remove | ||
419 | /sys/bus/pci/devices/.../rescan | ||
420 | |||
421 | there is no functional reason to maintain fakephp as well. | ||
422 | |||
423 | We will keep the existing module so that 'modprobe fakephp' will | ||
424 | present the old /sys/bus/pci/slots/... interface for compatibility, | ||
425 | but users are urged to migrate their applications to the API above. | ||
426 | |||
427 | After a reasonable transition period, we will remove the legacy | ||
428 | fakephp interface. | ||
