Fix file name when change attribute from a directory in linux

[julianmesa-gitkraken]

When you change an attribute in a directory the file name length can be 0 in the event (event->len) in linux, the event name property is optional.

           struct inotify_event {
               int      wd;       /* Watch descriptor */
               uint32_t mask;     /* Mask describing event */
               uint32_t cookie;   /* Unique cookie associating related
                                     events (for rename(2)) */
               uint32_t len;      /* Size of name field */
               char     name[];   /* Optional null-terminated name */
           };

question

Do we need to check event->name anywhere else?

Do we need to check event->name anywhere else?

I think is not required, but I have added it for security in all code
