[PATCH v8 11/32] fsnotify: Protect fsnotify_handle_inode_event from no-inode events

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



FAN_FS_ERROR allows events without inodes - i.e. for file system-wide
errors.  Even though fsnotify_handle_inode_event is not currently used
by fanotify, this patch protects this path to handle this new case.
