[PATCH v5 0/6] [GSoC] remove_subtree(): reimplement using iterators

[Daniel Ferreira <bnmvco@gmail.com>]

This is the fifth version of a patch series that implements the GSoC
microproject of converting a recursive call to readdir() to use dir_iterator.

I would like to really thank Michael for the incredibly thorough review of
the last version of this series. I never expected anyone to give that
level of attention to this change, and it's really, really appreciated.

All of the points he addressed are fixed in this version. As always, more
feedback is greatly appreciated.

Thanks,
Daniel.
