2012-11-29fix off-by-one in argument passed by iterate_fd() to callbacksAl Viro
Noticed by Pavel Roskin; the thing in his patch I disagree with was compensating for that shite in callbacks instead of fixing it once in the iterator itself. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-11-29nfs_lookup_revalidate(): fix a leakAl Viro
We are leaking fattr and fhandle if we decide that dentry is not to be invalidated, after all (e.g. happens to be a mountpoint). Just free both before that... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-11-29ext4: fix possible use after free with metadata csumTheodore Ts'o
Commit fa77dcfafeaa introduces block bitmap checksum calculation into ext4_new_inode() in the case that block group was uninitialized. However we brelse() the bitmap buffer before we attempt to checksum it so we have no guarantee that the buffer is still there. Fix this by releasing the buffer after the possible checksum computation. Signed-off-by: Lukas Czerner <lczerner@redhat.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Acked-by: Darrick J.

2012-11-29staging: panel: pass correct lengths to keypad_send_key()Dan Carpenter
We changed the sizeof() statements in 429ccf058b "staging:panel: Fixed coding conventions." so that they could fit inside the 80 character line limit. Unfortunately, the new sizeof() statements are a smaller size. This reverts it. There isn't a nice way to stay within the 80 character limit without a re-work so I've gone over.

2012-11-29ext4: restructure ext4_ext_direct_IO()Theodore Ts'o
Remove a level of indentation by moving the DIO read and extending write case to the beginning of the file. This results in no actual programmatic changes to the file, but makes it easier to read/understand. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2012-11-29staging: comedi: addi_apci_2032: fix interrupt supportH Hartley Sweeten
This board supports two interrupt sources: VCC : detects when the external supply voltage drops below 5V CC : over temperature diagnostic Currently the interrupt support is tied into the digital output subdevice. It's also broken since it does not follow the comedi API. Create a new digital input subdevice to handle the interrupts.

The timer subdevice does not have a digital range. Its range of 0 to 0xff is the value used to set the reload timer. Remove the setting of s->range_table. The comedi core will then set it to range_unknown.

2012-11-29staging: comedi: addi_apci_2032: fix the watchdog timer subdeviceH Hartley Sweeten
The watchdog timer on this board functions exactly like the one on the apci_1516 board. Fix the i_APCI2032_StartStopWriteWatchdog and i_APCI2032_ConfigWatchdo functions so that the watchdog follows the comedi API. Rename the CamelCase function i_APCI2032_StartStopWriteWatchdog to apci2032_wdog_insn_writ. This function is used to "ping" the watchdog. Rename the CamelCase function i_APCI2032_ConfigWatchdog to apci2032_wdog_insn_config. This function is used to enable/disable the watchdog and set the timeout.

2012-11-29staging: comedi: addi_apci_2032: remove use of struct addi_privateH Hartley Sweeten
The only data in addi_private used in this driver is: tsk_Current - used with send_sig to signal userspace when an interrupt has occurred. Interrupt support in this driver does not follow the standard comedi API so this functionality is currently broken. This will be addressed. b_OutputMemoryStatus - used in the addi-data "common" code to enable reading of the eeprom. Eeprom support is not needed by this driver and has been removed. Since this data is not needed, remove the use of struct addi_private.

The board supported by this driver has a 93c76 eeprom. Knowing this information allows simplifying the code that reads the PCI bars to get the iobase address.

2012-11-29blkdev_max_block: make private to fs/buffer.cLinus Torvalds
We really don't want to look at the block size for the raw block device accesses in fs/block-dev.c, because it may be changing from under us. So get rid of the max_block logic entirely, since the caller should already have done it anyway. That leaves the only user of this function in fs/buffer.c, so move the whole function there and make it static. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-11-29KVM: Fix user memslot overlap checkAlex Williamson
Prior to memory slot sorting this loop compared all of the user memory slots for overlap with new entries. With memory slot sorting, we're just checking some number of entries in the array that may or may not be user slots. Instead, walk all the slots with kvm_for_each_memslot, which has the added benefit of terminating early when we hit the first empty slot, and skip comparison to private slots.
