[PATCH 0/4] Remove posix_fallocate emulation [BZ#15661]

[Florian Weimer]

This patch series contains various fallocate-related cleanups
and removes the broken posix_fallocate emulation (which has
been observed to cause silent data loss in the wild).

Tested on i386-redhat-linux-gnu and x86_64-redhat-linux-gnu,
with no regressions.

Florian Weimer (4):
  posix_fallocate, posix_fallocate64 stub: Do not set errno
  i386: Remove fallocate, fallocate64, posix_fallocate,
    posix_fallocate64
  __ASSUME_FALLOCATE is always true on 32-bit architectures
  Remove broken posix_fallocate, posix_falllocate64 fallback code
    [BZ#15661]
