Assuming that the extension you proposed in <http://www.mail-archive.com/bug-coreutils@gnu.org/msg17684.html> is added to the Linux kernel, I suggest that coreutils modify the code to use 'inotify_add_watch_fd' instead of the current 'inotify_add_watch'. This will let "tail" watch stdin just like it can watch any other file descriptor. An added benefit of the fd approach is that it will fix a race condition in the current code, if a file is renamed between the call to 'open' and the call to 'inotify_add_watch_fd'. It should also simplify the "tail" code considerably to use an file-descriptor-based approach. In the meantime I would just leave the code alone; no sense wasting much time maintaining the inferior kernel interface.
