Pass mount flags to sget() so that it can use them in initialising a new
superblock before the set function is called. They could also be passed to the
compare function.

boolean "does it have to be exclusive?" flag is passed instead;
Local filesystem should just ignore it - the object is guaranteed
not to be there yet.

Just the flags; only NFS cares even about that, but there are
legitimate uses for such argument. And getting rid of that
completely would require splitting ->lookup() into a couple
of methods (at least), so let's leave that alone for now...

Just pass struct file *. Methods are happier that way...
There's no need to return struct file * from finish_open() now,
so let it return int. Next: saner prototypes for parts in
namei.c

Change of calling conventions:
old new
NULL 1
file 0
ERR_PTR(-ve) -ve
Caller *knows* that struct file *; no need to return it.

... and let finish_open() report having opened the file via that sucker.
Next step: don't modify od->filp at all.

Add an ->atomic_open implementation which replaces the atomic open+create

After we moved inode_sync_wait() from end_writeback() it doesn't make sense
to call the function end_writeback() anymore. Rename it to clear_inode()
which well says what the function really does - set I_CLEAR flag.

Pull 9p changes for the 3.4 merge window from Eric Van Hensbergen.
* tag 'for-linus-3.4-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/ericvh/v9fs:
9p: statfs should not override server f_type
net/9p: handle flushed Tclunk/Tremove
net/9p: don't allow Tflush to be interrupted
Allow a 9p2000.L server to supply the statfs f_type value rather than
hardwiring V9FS_MAGIC. It is desirable to give the server this option
in some applications, e.g. I/O forwarding.

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ericvh/v9fs:
fs/9p: iattr_valid flags are kernel internal flags map them to 9p values.
fs/9p: We should not allocate a new inode when creating hardlines.
fs/9p: v9fs_stat2inode should update suid/sgid bits.
9p: Reduce object size with CONFIG_NET_9P_DEBUG
fs/9p: check schedule_timeout_interruptible return value
Fix up trivial conflicts in fs/9p/{vfs_inode.c,vfs_inode_dotl.c} due to
debug messages having changed to use p9_debug() on one hand, and the
changes for umode_t on the other.
Kernel internal values can change, add protocol values for these constant
and use them.

Don't do new_inode_from fid in case of hardlink creation. This ensures

was not updated on removing a hardlink with cache mode enabled.

Reduce object size by deduplicating formats.
Use vsprintf extension %pV.
Rename P9_DPRINTK uses to p9_debug, align arguments.
Add function for _p9_debug and macro to add __func__.
Add missing "\n"s to p9_debug uses.
Remove embedded function names as p9_debug adds it.
Remove P9_EPRINTK macro and convert use to pr_<level>.
Add and use pr_fmt and pr_<level>.

In v9fs_file_do_lock() we need to check return value of
schedule_timeout_interruptible() and exit the loop when it
returns nonzero, otherwise the loop is not really interruptible
and after the signal, the loop is no longer throttled by
P9_LOCK_TIMEOUT.

Pass perm to v9fs_vfs_mkspecial() instead of passing mode;
calculate in caller when done for mknod(), use known value for link()
and symlink(). As the result, we avoid a bit of work *and* stop
mixing mode_t with P9_DMLINK.
