The 2.6.30 kernel generates this warning:
uvc_driver.c:1729: warning: 'ret' may be used uninitialized in this function
I guess some new warning flag must have been turned on since this warning
didn't appear with older kernels (gcc version 4.3.1). It's also a bogus
warning, but since this code didn't comply to the coding standard anyway
I've modified it to 1) remove the warning and 2) conform to the coding
standard.

Some ioctls have structs that are a different size depending on what type
of buffer is being used. If the buffer type leaves a field unused or has
padding space at the end, this space should be zeroed out.
The problems with S_FMT and REQBUFS were original identified and patched by
Marton Nemeth <nm127@freemail.hu>.

For a number of different ioctls, the v4l2-ioctl code checks that the
passed buffer type is supported by the driver. It did this by checking
that the driver defined a method for the try_fmt handler for that buffer
type. However, try_fmt is optional and a driver might not provide it even
though it does support that type. So use g_fmt instead, since that isn't
optional.
This should fix a problem with VBI capture with saa7146.

If someone requests a format at fmt->index == (unsigned)-1 and the first
format in the array doesn't have the requested type then num will still be
-1 when it's compared to fmt->index and there will appear to be a match.
Restructure the loop so this can't happen. It's simpler this way too. The
unnecessary check for (unsigned)fmt->index < 0 found by Roel Kluin
<roel.kluin@gmail.com> is removed this way too.

Now urb buffers is not freed before suspend, so uvc_alloc_urb_buffers should
return packet counts allocated originally during uvc resume, instead of zero.
This version uses round down to return packet counts on Linus' suggestions,
or else may lead to buffer destructed if packet size is changed before
calling uvc_alloc_urb_buffers() in this kind of case.

If module initialisation failed (e.g. because the bonding sysfs entry
cannot be created), kernel panics:
IP: [<ffffffff8024910a>] destroy_workqueue+0x2d/0x146
Call Trace:
[<ffffffff808268c4>] bond_destructor+0x28/0x78

Remove the calls to bond_work_cancel_all() and destroy_workqueue();
both are also called/scheduled via bond_free_all().
bond_destroy_sysfs is unecessary because the sysfs entry has
not been created in the error case.

Does equivalent of up_write(&s->s_umount); deactivate_super(s);
However, it does not does not unlock it until it's all over.
As the result, it's safe to use to dispose of new superblock on ->get_sb()
failure exits - nobody will see the sucker until it's all over.
Equivalent using up_write/deactivate_super is safe for that purpose
if superblock is either safe to use or has NULL ->s_root when we unlock.
Normally filesystems take the required precautions, but
a) we do have bugs in that area in some of them.
b) up_write/deactivate_super sequence is extremely common,
so the helper makes sense anyway.

With Al Viro's patch to move privroot lookup to fs mount, there's no need

The xattr_root caching was broken from my previous patch set. It wouldn't
cause corruption, but could cause decreased performance due to allocating
a larger chunk of the journal (~ 27 blocks) than it would actually use.
This patch loads the xattr root dentry at xattr initialization and creates
it on-demand. Since we're using the cached dentry, there's no point
in keeping lookup_or_create_dir around, so that's removed.

2.6.30-rc3 introduced some sanity checks in the VFS code to avoid NFS
bugs by ensuring that lookup_one_len is always called under i_mutex.
This patch expands the i_mutex locking to enclose lookup_one_len. This was
always required, but not not enforced in the reiserfs code since it
does locking around the xattr interactions with the xattr_sem.
This is obvious enough, and it survived an overnight 50 thread ACL test.

This fixes the following circular locking dependency problem:
=======================================================
[ INFO: possible circular locking dependency detected ]
2.6.30-rc3 #5
-------------------------------------------------------
segctord/3895 is trying to acquire lock:
(&nilfs->ns_writer_mutex){+.+...}, at: [<d0d02172>]
nilfs_mdt_get_block+0x89/0x20f [nilfs2]
but task is already holding lock:
(&bmap->b_sem){++++..}, at: [<d0d02d99>]
nilfs_bmap_propagate+0x14/0x2e [nilfs2]
which lock already depends on the new lock.
The bugfix is done by replacing call sites of nilfs_get_writer() which
are never called from read-only context with direct dereferencing of
pointer to a writable FS-instance.

Some function calls in nilfs_prepare_segment_for_recovery() may fail
because they can create blocks on meta data files without configuring
a writable FS-instance. Concretely, nilfs_mdt_create_block() routine
of meta data files will fail in that case.
This fixes the problem by temporarily attaching a writable FS-instace
during the function is called.

This patch (as1238) adds proper reference counting for ftdi_sio's
private data structure. Without it, the driver will free the
structure while it is still in use if the user unplugs the serial
device before closing the device file.
The patch also replaces a slightly dangerous
cancel_delayed_work/flush_scheduled_work pair with
cancel_delayed_work_sync, which is always safer.
