In the Linux kernel, the following vulnerability has been resolved:
eventfs: Fix a possible null pointer dereference in eventfs_find_events()
In function eventfs_find_events,there is a potential null pointer
that may be caused by calling update_events_attr which will perform
some operations on the members of the ei struct when ei is NULL.
Hence,When ei->is_freed is set,return NULL directly.
