It should've been changed when queue_work() became
queue_delayed_work(..., 0) in there. It's always had been
about not needing a delay, not about not using specific
function...

Adds support for qnx6fs readonly support to the linux kernel.
* Mount option
The option mmi_fs can be used to mount Harman Becker/Audi MMI 3G
HDD qnx6fs filesystems.
* Documentation
A high level filesystem stucture description can be found in the
Documentation/filesystems directory. (qnx6.txt)
* Additional features
- Active (stable) superblock selection
- Superblock checksum check (enforced)
- Supports mount of qnx6 filesystems with to host different endianess
- Automatic endianess detection
- Longfilename support (with non-enfocing crc check)
- All blocksizes (512, 1024, 2048 and 4096 supported)

First of all, there's no need to zero ->i_uid/->i_gid on root inode -
both had been set to zero already. Moreover, let's take the iput()
on failure to the failure exit it belongs to...

Once upon a time it used to be much bigger, but these days there's
no point whatsoever keeping it in fs/inode.c, especially since
it's not even needed as initializer for ->drop_inode() - it's the
default and leaving ->drop_inode NULL will do just as well.

New field of struct super_block - ->s_max_links. Maximal allowed
value of ->i_nlink or 0; in the latter case all checks still need
to be done in ->link/->mkdir/->rename instances. Note that this
limit applies both to directoris and to non-directories.

Minor cleanup. de_thread()->setmax_mm_hiwater_rss() looks a bit
strange, move it into exec_mmap() which plays with old_mm.

exit_notify() checks "tsk->self_exec_id != tsk->parent_exec_id"
to handle the "we have changed execution domain" case.
We can change do_thread() to always set ->exit_signal = SIGCHLD
and remove this check to simplify the code.
We could change setup_new_exec() instead, this looks more logical
because it increments ->self_exec_id. But note that de_thread()
already resets ->exit_signal if it changes the leader, let's keep
both changes close to each other.
Note that we change ->exit_signal lockless, this changes the rules.
Thereafter ->exit_signal is not stable under tasklist but this is
fine, the only possible change is OLDSIG -> SIGCHLD. This can race
with eligible_child() but the race is harmless. We can race with
reparent_leader() which changes our ->exit_signal in parallel, but
it does the same change to SIGCHLD.
The noticeable user-visible change is that the execing task is not
"visible" to do_wait()->eligible_child(__WCLONE) right after exec.
To me this looks more logical, and this is consistent with mt case.

Here's the big serial and tty merge for the 3.4-rc1 tree.
There's loads of fixes and reworks in here from Jiri for the tty layer,
and a number of patches from Alan to help try to wrestle the vt layer
into a sane model.
Other than that, lots of driver updates and fixes, and other minor
stuff, all detailed in the shortlog.
