I didn't quite follow this part of the discussion.
Do not eliminate d_reclen from struct dirent. I've found it useful
from time-to-time to store additional values after d_name in a
dirent record (for example, the NFS cookies). Expect dirents to
become more complicated over time. Deriving the record length
from d_namlen alone will become impossible and it becomes quite
awkward to reliably calculate the d_reclen without the variable.
