configfs: Convert subsystem semaphore to mutex
Convert the su_sem member of struct configfs_subsystem to a struct mutex, as that's what it is. Also convert all the users and update Documentation/configfs.txt and Documentation/configfs_example.c accordingly. [ Conflict in fs/dlm/config.c with commit 3168b0780d06ace875696f8a648d04d6089654e5 manually resolved. --Mark ] Inspired-by: Satyam Sharma <ssatyam@cse.iitk.ac.in> Signed-off-by: Joel Becker <joel.becker@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
