From c9482a5bdcc09be9096f40e858c5fe39c389cd52 Mon Sep 17 00:00:00 2001 From: Jianyu Zhan Date: Sat, 26 Apr 2014 15:40:28 +0800 Subject: kernfs: move the last knowledge of sysfs out from kernfs There is still one residue of sysfs remaining: the sb_magic SYSFS_MAGIC. However this should be kernfs user specific, so this patch moves it out. Kerrnfs user should specify their magic number while mouting.
