Subject: [PATCH] mod_sysfs_setup() doesn't return errno when kobject_add_dir() failure occurs
Date: Sat, 14 Apr 2007 15:08:12 +0900 [thread overview]
Message-ID: <20070414060812.GA25130@APFDCB5C> (raw)
mod_sysfs_setup() doesn't return an errno when kobject_add_dir()
for module "holders" directory fails. So caller of mod_sysfs_setup()
will keep going and get oops.
