Latest commit 1abf257 Jan 11, 2018 @edsiper edsiper in_tail: inotify: double check if IN_ATTRIB is a file deletion
there some cases where unlink(2) triggers a IN_ATTRIB inotify
event (rm command), but also a chmod(2) triggers the same event
leading to a false file deletion.

This patch makes sure that when IN_ATTRIB event is received
checks the stat nlink of the file, if it's zero means it was
a real "deletion".
