Nor does it apply to v2.6.35-rc4:

 Applying: writeback: simplify the write back thread queue
 error: patch failed: fs/fs-writeback.c:703
 error: fs/fs-writeback.c: patch does not apply
 Patch failed at 0001 writeback: simplify the write back thread queue

I guess it has other dependencies as well. If you want me to test the fix then 
please send a version that applies.

Thanks,
