Umm... As I applied this changes manually there is a not insignificant
change of goofups on my part...
For the hang problem I think Tronds suggestion with replacing the
patches from -mm with fresh versions would be the best.
Anyway, currently I have the patch from
http://lkml.org/lkml/2007/11/16/74 to fix the can't-create-files-bug.
To fix the hang bug I used Tronds
linux-2.6.24-007-fix_nfs_free_unlinkdata.dif and the first two hunks
from linux-2.6.24-006-fix_to_fix_sillyrename_bug_on_umount.dif.
