151fc5dfc8 PCI: drivers/pci/pci-sysfs.c: Add missing pci_dev_put
There should be a pci_dev_put when breaking out of a loop that iterates

f1e8de0dbb USB: usb-storage: unusual_devs entry for JetFlash TS1GJF2A
This patch (as1018) adds an unusual_devs entry for the JetFlash
TS1GJF2A.  This device doesn't like read requests for more than 188
sectors.  Setting max_sectors down to 64 is overkill, but at least
it will work without errors.

4a9bee8256 USB: uevent environment key fix
This patch (as1010) was written by both Kay Sievers and me.  It solves
the problem of duplicated keys in USB uevent structures by refactoring
the uevent subroutines, taking advantage of the way the hotplug core
calls uevent handlers for the device's bus and for the device's type.
Keys needed for both USB-device and USB-interface events are added in
usb_uevent(), which is the bus handler.  Keys appropriate only for
USB-device or USB-interface events are added in usb_dev_uevent() or
usb_if_uevent() respectively, the type handlers.

In addition, unnecessary tests for NULL pointers are removed as are
duplicated debugging log statements.

simply adds a flag to keep track of whether or not the files have been

f08812d5eb USB: FIx locks and urb->status in adutux (updated)
Two main issues fixed here are:
 - An improper use of in-struct lock to protect an open count
 - Use of urb status for -EINPROGRESS

Also, along the way:
 - Change usb_unlink_urb to usb_kill_urb. Apparently there's no need
   to use usb_unlink_urb whatsoever in this driver, and the old use of
   usb_kill_urb was outright racy (it unlinked and immediately freed).
 - Fix indentation in adu_write. Looks like it was damaged by a script.
 - Vitaly wants -EBUSY on multiply opens.
 - bInterval was taken from a wrong endpoint.

8118a859dc sysfs: fix off-by-one error in fill_read_buffer()
I found that there is a off-by-one problem in the following code.

Version:	2.6.24-rc2
File:		fs/sysfs/file.c:118-122
Function:	fill_read_buffer
--------------------------------------------------------------------
	count = ops->show(kobj, attr_sd->s_attr.attr, buffer->page);

	sysfs_put_active_two(attr_sd);

	BUG_ON(count > (ssize_t)PAGE_SIZE);
--------------------------------------------------------------------

Because according to the specification of the sysfs and the implement of
the show methods, the show methods return the number of bytes which would
be generated for the given input, excluding the trailing null.So if the
return value of the show methods equals PAGE_SIZE - 1, the buffer is full
in fact.  And if the return value equals PAGE_SIZE, the resulting string
was already truncated,or buffer overflow occurred.

This patch fixes an off-by-one error in fill_read_buffer.

dec13c1544 create /sys/.../power when CONFIG_PM is set
The CONFIG_SUSPEND changes in 2.6.23 caused a regression under certain
configuration conditions (SUSPEND=n, USB_AUTOSUSPEND=y) where all USB
device attributes in sysfs (idVendor, idProduct, ...) silently disappeared,
causing udev breakage and more.

The cause of this is that the /sys/.../power subdirectory is now only
created when CONFIG_PM_SLEEP is set, however, it should be created whenever
CONFIG_PM is set to handle the above situation.  The following patch fixes
the regression.

d393820446 softlockup: fix false positives on CONFIG_NOHZ
David Miller reported soft lockup false-positives that trigger
on NOHZ due to CPUs idling for more than 10 seconds.

The solution is touch the softlockup watchdog when we return from
idle. (by definition we are not 'locked up' when we were idle)

b1967d0edd ocfs2: reverse inline-data truncate args
ocfs2_truncate() and ocfs2_remove_inode_range() had reversed their "set
i_size" arguments to ocfs2_truncate_inline(). Fix things so that truncate
sets i_size, and punching a hole ignores it.

This exposed a problem where punching a hole in an inline-data file wasn't
updating the page cache, so fix that too.

This was causing us to prematurely push out inline data by one byte.
