From 270c31284f7d05557a31ef1304d582897bf4ffcc Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Wed, 13 Nov 2013 06:40:25 +0000 Subject: [PATCH] xfsprogs: fix automatic dependency generation Adding are removing a header file does not result in dependency regeneration like it should. 'make clean' will rebuild the dependencies, but a normal 'make' won't. Fix it.
