sortix--sortix/libmaxsi/dup.cpp
Jonas 'Sortie' Termansen 01df97080e Refactored libmaxsi/io.cpp into multiple files.
This creates more object files in the static library which reduces the size
of statically linked files as only the relevant object files are included.
In my experience, it reduced the size of the system initrd from 1.9 MiB to
1.6 MiB which is valuable.
