Subject: [PATCH 10/15] xfsprogs: make static things static
Date: Thu,  4 Oct 2018 23:03:11 -0500	[thread overview]
Message-ID: <1538712196-13625-11-git-send-email-sandeen@sandeen.net> (raw)
In-Reply-To: <1538712196-13625-1-git-send-email-sandeen@sandeen.net>

From: Eric Sandeen <sandeen@redhat.com>

There are tons of functions which can be static, make them so.

Fixes many sparse warnings about this.
