From 6450084a66b6cf72b9126a8c8ecead7ddca896e9 Mon Sep 17 00:00:00 2001 From: Keno Fischer Date: Sun, 27 Feb 2022 17:35:13 -0500 Subject: 9p: Rename 9p-util -> 9p-util-linux MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The current file only has the Linux versions of these functions. Rename the file accordingly and update the Makefile to only build it on Linux. A Darwin version of these will follow later in the series.
