From fac2622bbad4d7e3a32c53e631e018b80ec631dc Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Fri, 12 Feb 2010 19:22:27 -0800 Subject: [PATCH] sysfs: Pass super_block to sysfs_get_inode Currently sysfs_get_inode magically returns an inode on sysfs_sb. Make the super_block parameter explicit and the code becomes clearer. Acked-by: Tejun Heo Acked-by: Serge Hallyn Signed-off-by: Eric W.
