From 3782b59e8f6391134cf146033ebe3baa1fbc0f5a Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Mon, 16 Apr 2018 14:30:12 +0200 Subject: [PATCH] libfstools: add "const" to char pointer arguments in mount_move() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit That function never modifies these strings so it can/should use consts. It makes it a bit more flexible as now callers can also pass consts.
