Subject: [RESEND PATCH] kconfig: allow kconfig to handle longer path names
Date: Wed, 9 Dec 2015 14:56:12 -0800	[thread overview]
Message-ID: <1449701772-25095-1-git-send-email-mmayer@broadcom.com> (raw)

The current (arbitrary) limit of 128 characters for path names has
proven too short for Android builds, as longer path names are used
there.

Change conf.c, so it can handle path lengths up to PATH_MAX characters.
