[PATCH 0/4] Move libio lock single-thread optimization to generic libc-lock

[Adhemerval Zanella]

This patchset removes some old unused code (_IO_lock_inexpensive
and _IO_MTSAFE_IO), consolidate the stdio-lock.h and move the
single-thread lock optimization to generic code instead of
per-function usage.

Adhemerval Zanella (4):
  libio: Assume _IO_lock_inexpensive
  libio: Assume _IO_MTSAFE_IO
  Consolidate stdio-lock.h
  Move libio lock single-thread optimization to generic libc-lock (BZ
    #27842)
