Comment:

 Thanks for your interest in the RTEMS port of JFFS2. If you have
 questions, then you could also ask them on the devel at rtems.org mailing
 list. The RTEMS port of JFFS2 does not use a file system internal locking.
 There is a global lock for each JFFS2 instance:
 {{{#!c
 static void rtems_jffs2_do_lock(struct super_block *sb)
 {
         rtems_recursive_mutex_lock(&sb->s_mutex);
 }

 static void rtems_jffs2_do_unlock(struct super_block *sb)
 {
         rtems_recursive_mutex_unlock(&sb->s_mutex);
 }
 }}}
