+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.
