civodul pushed a commit to branch master
in repository guix.

commit dae956e7961ea4940a3823a7b33f8264196ca594
Author: Sören Tempel <soeren@soeren-tempel.net>

    syscalls: Consistently use existing linux? definition.
    
    Instead of duplicating this existing logic across the source file. This
    will make it easier to add additional linux targets (e.g. linux-musl) in
    the future.
    
    * guix/build/syscalls.scm (readdir*, write-socket-address!)
    (read-socket-address): Use linux? constant.
