fbdefio: add set_page_dirty handler to deferred IO FB

2008-08-20T22:40:32+00:00

Fixes kernel BUG at lib/radix-tree.c:473.

Previously the handler was incidentally provided by tmpfs but this was
removed with:

  commit 14fcc23fdc78e9d32372553ccf21758a9bd56fa1
  Author: Hugh Dickins

    tmpfs: fix kernel BUG in shmem_delete_inode

relying on this behaviour was incorrect in any case and the BUG also
appeared when the device node was on an ext3 filesystem.

v2: override a_ops at open() time rather than mmap() time to minimise
races per AKPM's concerns.

rtc: rtc-ds1374: fix 'no irq' case handling

2008-08-20T22:40:32+00:00

On a PowerPC board with ds1374 RTC I'm getting this error while RTC tries
to probe:

rtc-ds1374 0-0068: unable to request IRQ

This happens because I2C probing code (drivers/of/of_i2c.c) is specifying
IRQ0 for 'no irq' case, which is correct.

The driver handles this incorrectly, though. This patch fixes it.

rtc: fix double lock on UIE emulation

2008-08-20T22:40:31+00:00

With commit 5ad31a575157147b43fa84ef1e21471661653878 ("rtc: remove BKL
for ioctl()"), RTC_UIE_ON ioctl cause double lock on rtc->ops_lock.
The ops_lock must not be held while set_uie() calls rtc_read_time()
which takes the lock.  Also clear_uie() does not need ops_lock.  This
patch fixes return value of RTC_UIE_OFF ioctl too.

brd: fix name argument of unregister_blkdev()

2008-08-20T22:40:30+00:00

The name of brd block device is "ramdisk", it's not "brd".
(The block device is registered by register_blkdev(RAMDISK_MAJOR, "ramdisk")
So it should be unregistered by unregister_blkdev(RAMDISK_MAJOR, "ramdisk")

nbd: fix memory leak of nbd_dev array

2008-08-20T22:40:30+00:00

We leak the memory allocated for the nbd_dev array at multiple places.
Fix them by either adding a kfree() or by rearranging code to return
before we allocate the memory.
