Subject: Re: [PATCH 00/36] Remove UCLINUX from LTP

Hi!

My 2 cents. I'm working on refactoring growfiles test which uses UCLINUX 
flag.
During its development I had occasion to check UCLINUX support and 
(indeed) it seems pretty
broken for LTP, because nobody is maintaining it for a while and such 
tests use old API that will
be replaced in any case sooner or later. I agree with other people about 
removing it, unless there's
a valid reason to keep it.
Just in case we want to keep it, someone should take care about UCLINUX 
support, testing LTP releases for it as well, but it doesn't seem like 
something we can do inside the LTP devs team due to the lack of resources.

Regards,
Andrea
