Steven Rostedt (Google) 2598bd3ca8 eventfs: Test for dentries array allocated in eventfs_release() ... The dcache_dir_open_wrapper() could be called when a dynamic event is being deleted leaving a dentry with no children. In this case the dlist->dentries array will never be allocated. This needs to be checked for in eventfs_release(), otherwise it will trigger a NULL pointer dereference.
