This is a heads up for the Debian Kernel Team, though you likely are aware of the problem already.
There is a bug affecting NFS version 4 server (nfsd), and the patch has now hit Linus' tree: commit fffaee365fded09f9ebf2db19066065fa54323c3 Author: Konstantin Khlebnikov <khlebni...@openvz.org> Date: Tue Jun 5 21:36:33 2012 +0400 radix-tree: fix contiguous iterator This patch fixes bug in macro radix_tree_for_each_contig(). If radix_tree_next_slot() sees NULL in next slot it returns NULL, but follow radix_tree_next_chunk() switches iterating into next chunk. As result iterat becomes non-contiguous and breaks vfs "splice" and all its users.

I don't see any reference to the above NFS-related patch, so don't be surprised if you get some bug reports!
