An nfs question ftruncate vs. pwrite

[Kenny Simpson]

When a file that is opened with normal flags (O_RDWR|O_CREAT|O_TRUNC|O_LARGEFILE) is on NFS, and
it is exteded via ftruncate, the new expty pages get read back from the server before the system
call returns:
  (from strace -T):
ftruncate64(3, 41943040)                = 0 <0.063866>
