I've applied this this patch and the two recent userpace patches and it works 
alright, with one surprise -- two suspiciously large BLKCNT:

$ lscp -b
(...snip...)
              270584  2011-03-01 12:52:57   cp    -           33     248244
              270585  2011-03-01 12:53:01   cp    -           34     248245
              270586  2011-03-01 12:53:06   cp    - 18446744073709550523     
248245
              270587  2011-03-01 12:53:11   cp    - 18446744073709550550     
248257
              270588  2011-03-01 12:53:15   cp    -         1268     248247
              270589  2011-03-01 12:53:16   cp    -         1803     248246
              270590  2011-03-01 12:53:21   cp    -         4952     248256
(...snip...)


It is possible the two strange checkpoints (270586 & 7) were created with new 
userland and old kernel, before reboot.

Do you want me to provide any extra info on it or just let it slip?

iterators, string objects, and a full set of C macros that ensure
boundary conditions and improve interfaces.
