[PATCH] D39464: Define fs::allocate_file which preallocates disk blocks.

[Michał Górny via Phabricator via llvm-commits]

mgorny added inline comments.


================
Comment at: llvm/lib/Support/Unix/Path.inc:443
+#ifdef HAVE_FALLOCATE
+  if (fallocate(FD, 0, 0, Size) == -1)
+    return std::error_code(errno, std::generic_category());
----------------
Any reason not to use `posix_fallocate()` which is more portable by definition?
