ocfs2: embed kobject in ocfs2_super structure
fs/ocfs2/filecheck.c
Embed kobject in ocfs2_super structure, then we can use container_of
method to get our own data pointor via kobject pointer. Second, I adjust
the related code in create/remove online file check sysfs entry.

Hi Eric,
Looks good for me.
Just one suggestion,
please monitor if the LVB sharing mechanism in the cluster still works well in
the normal scenario,
to avoid any performance decrease regression problem.

Compare with first version, I use strncasecmp instead of double strncmp
functions. Second, update the source file contribution vendor.
