Changes since the last version (based on Al's review):
- cross-rename: fix locking of nondirectories for NFSv4
- ext4: split cross-rename and plain rename into separate functions
- introduce i_op->rename2 with flags, don't touch ->rename
- last (optional) patch to merge ->rename2 back into ->rename
The splitting of the ext4 implemetation was indeed a good idea as it uncovered a
memory leak and small inconsistencies with the merged implementation.
Splitting out rename2 will lessen the code churn, but I think is ugly. However
this is a question of taste, last patch can be ommitted without loss of
functionality.
Bruce, could you please review the locking and delegation thing in patch #8
"vfs: add cross-rename"?

Thanks,
Miklos
