> 1. Convert sendfile02 to the new API with file descriptors instead
> of socket descriptors.
> 2. Remove the support for UCLINUX.
> 3. Remove redundant testcases {4, 22, 26} and {6, 20, 26}.

Thanks, merged with diff below (fix docparse formatting, add OFFSET_DESC()
macro, fix checkpatch.pl warning on comparison order).

Kind regards,
Petr
