[PATCH 0/7] More efficient I/O

[Eric Blake]

I first noticed this while working on my NBD driver.  While this
doesn't completely batch up large I/O, it sure makes 64-bit access
more efficient.

Eric Blake (7):
  ios: Drop Position column from .info ios
  ios: Pass offset to low-level macros.
  ios: Prove we don't need seek.
  ios: Drop unused seek/tell callbacks.
  ios: Change from getchar to pread device interface.
  ios: Utilize buffer reads.
  ios: Utilize buffer writes.
