First of all, thanks for the overwhelming response!
Based on the suggestions received, I have added a new parameter to the
sys_fallocate() system call - an interger called mode, just after the
fd. Now the system call looks like this:
asmlinkage long sys_fallocate(int fd, int mode, loff_t
XFS currently defines various fid types internally, including an
fid_t which I will introduce kernel wide in the next patch.
This patch kills the fid_t and xfs_fid2_t types inside xfs and uses
xfs_fid_t consistantly.

Add a structured fid type so that we don't have to pass an array
of u32 values around everywhere. It's a union of possible layouts.
As a start there's only the u32 array and the traditional 32bit
inode format, but there will be more in one of my next patchset

Add the guts for the new filesystem API to exportfs.
There's now a fh_to_dentry method that returns a dentry for the
object looked for given a filehandle fragment, and a fh_to_parent
operation that returns the dentry for the encoded parent directory
in case the file handle contains it.

Nice little cleanup by consolidating things a little and using
a structure for the special file handle format.

Convert gfs2 to the new ops. It's a nice little cleanup that allows
to get rid of an data structure aswell.
Btw, it looks like the old code could scribble over random stack
memory for the parent case where gfs2_get_dentry access the imode
field in the gfs2_fh_obj structure but only gets a

method descruptions in exportfs.h and point to Documentation/filesystems/

I'm interested in understanding the state of Linux with regard to
_really_ forcing a filesystem to unmount.
There is a (stale) project at OSDL that has various implementations:
http://developer.osdl.org/dev/fumount/
Its fairly clear that these efforts (e.g. badfs patches) haven't been
given

Have a look at all the discussion about revoke/frevoke on lkml over the
last week or two.
