From 599662c538d06054608b16a1d6a3ce10f4fdd08c Mon Sep 17 00:00:00 2001 From: Brian Behlendorf Date: Thu, 2 Oct 2014 14:48:23 -0400 Subject: [PATCH] Remove kern_path() wrapper The kern_path() function has been available since Linux 2.6.28. There is no longer a need to maintain this compatibility code.
