This patch (hack?) works around the slowness in SEEK_HOLE for large dense files on Linux tmpfs. It may improve life elsewhere as well, and the penalty of the checks should be vanishingly small where it is not needed.
If I'm subtly (or not so subtly) wrong, please fire back. Sincerely, -- Christopher Oliver <current.input.p...@gmail.com>
