[PATCH 0/5] Concurrent O_SYNC write speedups using radix-tree walks

[Suparna Bhattacharya]

The attached patches (generated against 2.6.8-rc2) enable concurrent 
O_SYNC writers to different parts of the same file by avoiding 
serialising on i_sem across the wait for IO completion.

This is mostly your work, ported to the tagged radix tree VFS changes
and a few fixes. I have been carrying these patches for sometime now; 
they can be the merged upstream. Please apply.

Regards
Suparna
