[0/6] Prepare for fanotify name events

Message

Jan,

Fanotify name event patches are ready at [1].
I am still updating the tests and the demo.

In the mean while, I wanted to post these few prep patches including
two bug fixes, so perhaps you will be able to process them in time for
v5.6-rc1.

Patches 1-4 are just cleanup and minor re-factoring in prep for the
name event patches.

Patches 5-6 are fixes for minor bug that I found during the work.
I improved ltp tests fanotify09 and fanotify15 to cover these bugs [2].

I did not mark those patches for stable, because backporting is not
trivial and the bugs are really minor.  For the same reason, I did
not bother to provide bug fix patches that are not dependent on the
cleanup patches, although that might have been possible to do.

Thanks,
Amir.
