quota: unify quota init condition in setattr
Quota must being initialized if size or uid/git changes requested.
But initialization performed in two different places:
in case of i_size file system is responsible for dquot init
, but in case of uid/gid init will be called internally in
dquot_transfer().
This ambiguity makes code harder to understand.
Let's move this logic to one common helper function.

ext3: make barrier options consistent with ext4
ext4 was updated to accept barrier/nobarrier mount options
in addition to the older barrier=0/1. The barrier story
is complex enough, we should help people by making the options
the same at least, even if the defaults are different.
This patch allows the barrier/nobarrier mount options for ext3,
while keeping nobarrier the default.
It also unconditionally displays barrier status in show_options,

BKL: Remove BKL from ext2 filesystem
The BKL is still used in ext2_put_super(), ext2_fill_super(), ext2_sync_fs()
ext2_remount() and ext2_write_inode(). From these calls ext2_put_super(),
ext2_fill_super() and ext2_remount() are protected against each other by
the struct super_block s_umount rw semaphore. The call in ext2_write_inode()
could only protect the modification of the ext2_sb_info through
ext2_update_dynamic_rev() against concurrent ext2_sync_fs() or ext2_remount().
ext2_fill_super() and ext2_put_super() can be left out because you need a
valid filesystem reference in all three cases, which you do not have when
you are one of these functions.

safely be removed since this is protected by the struct ext2_sb_info s_lock.

USB: ir-usb: allow custom bulk buffer size without reallocation
Use usb_serial_driver bulk_in_size and bulk_out_size to make sure
buffers of appropriate sizes are allocated in the first place rather than
reallocating them at every open.

USB: EHCI: fix controller wakeup flag settings during suspend
This patch (as1380) fixes a bug in the wakeup settings for EHCI host
controllers. When the controller is suspended, if it isn't enabled
for remote wakeup then we have to turn off all the port wakeup flags.
Disabling PCI PME# isn't good enough, because some systems (Intel)
evidently use alternate wakeup signalling paths.
In addition, the patch improves the handling of the Intel Moorestown
hardware by performing various power-up and power-down delays just
once instead of once for each port (i.e., the delays are moved outside
of the port loops). This requires extra code, but the total delay
time is reduced.
There are also a few additional minor cleanups.

USB: EHCI: clear PHCD before resuming
This is a bug fix for PHCD (phy clock disable) low power feature:
After PHCD is set, any write to PORTSC register is illegal, so when
resume ports, clear PHCD bit first.
