From: Rafał Miłecki Date: Mon, 16 Apr 2018 12:30:12 +0000 (+0200) Subject: libfstools: add "const" to char pointer arguments in mount_move() X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3782b59e8f6391134cf146033ebe3baa1fbc0f5a;p=project%2Ffstools.git libfstools: add "const" to char pointer arguments in mount_move() 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.
