Phew! So I went through the patches. I didn't find any bug besides couple
of typos I've fixed and then couple of things I've flagged at individual
patches (which I've fixed up locally as well). There's just that
ignore_mask handling issue outstanding. Overall I have to say I'm unhappy
about the complexity of juggling with dir/inode/child, dirfh vs objfh, etc.
I acknowledge that the stuff is at least well commented so I was able to
grok it but still... That being said I don't have a great idea how to
simplify all this so at this point I'm ok with merging things as they are
but once all the functionality is in I want to have a look at how to
simplify all the special cases.
Anyway, for now, thanks for your persistence and work when developing this
series!
Honza
