Hi,
This patch implements a new cookie encoding scheme for encoding, decoding
and filling directory entries. This new scheme prevents duplicate cookies,
so it eliminates the need to sort the entries to prevent duplicates.
Thus, it simplies the code greatly.
Regards,
Bob Peterson

This stuff is around -atomic_open() and my main goal here is to eliminate the
cases when d_splice_alias() is used on a hashed dentry. Patches in question
sit in vfs.git#for-gfs2, and that branch isn't going to be rebased; I'd prefer
if it was pulled instead of having them applied manually.
In -atomic_open(inode, dentry, file, opened) calling finish_no_open(file, NULL)
is equivalent to dget(dentry); return finish_no_open(file, dentry);
No need to open-code that...

dentry is always hashed and negative, inode - non-error, non-NULL and
non-directory. In such conditions d_splice_alias() is equivalent to
d_instantiate(dentry, inode) and return NULL, which simplifies the
downstream code and is consistent with the have to create a new object
case.

vfree() is allowed under spinlock these days, but it's cheaper when
it doesn't step into deferred case and here it's very easy to avoid.
