[Bug libc/1083] New: fix posix_fallocate semantics using ftruncate


This trunk patch should go into the 2.3 branch:

2005-06-14  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/posix/posix_fallocate64.c: Use __libc_pread64 instead of
	__pread64.

2005-04-29  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/posix/posix_fallocate.c (posix_fallocate): If len == 0,
	call ftruncate if offset is bigger than current size.  Make sure
	the file is offset + len bytes long if that is more than current size.
	Don't overwrite previous content of the file.
	* sysdeps/posix/posix_fallocate64.c (__posix_fallocate64_l64):
	Likewise.
