xfstest generic/041 was taking some time before failing,
so this series aims to fix it and speed up.
Because of this we raise hardlinks limit to 4000.
There are no drawbacks or regressions.
Theoretically we can raise all the way up to ffff,
but there is no practical use for this.

Do not try to insert attribute if there is no room in record.

xfstest generic/041 works with 3003, so we need to raise limit.

This allows to wait only when it's requested.
It speeds up creation of hardlinks.

Hi. Sorry for taking so long. Did not notice that this is actually
another version. Please use v2 in subject. I did ask you to write little
bit more to commit "Change max hardlinks limit to 4000". Now you have
write it here. Cover letter will not be in commit messages. You need to
write this info to commit message also.

And it would be good to write generic/041. This way grepping is little
easier.
