Was the file name < 255 bytes?

That depends. This is in /usr/include/linux/limits.h

#define NAME_MAX         255    /* # chars in a file name */
#define PATH_MAX        4096    /* # chars in a path name including nul */

if (req->pathlen >= PATH_MAX)
                goto audit_receive_watch_exit;

Looks like it should allow only 4095 byte names through.
