Subject: [PATCH] libc: add fallocate() and fallocate64()
We add the Linux-specific function fallocate() which allows the user to
directly manipulate allocate space for a file. fallocate() can operate
in different modes, but the default mode is equivalent to posix_fallocate()
which is specified in POSIX.1.
Recent releases of e2fsprogs 1.42.11 and above expect fallocate64() to be
available.
