Subject: [newlib-cygwin] Cygwin: /proc/sys FS: don't export NFS and DFS as block devices
Date: Tue,  1 Dec 2020 08:40:18 +0000 (GMT)	[thread overview]
Message-ID: <> (raw);h=80e35a211f69f23fa57003a08d1758657364f00e

commit 80e35a211f69f23fa57003a08d1758657364f00e
Author: Corinna Vinschen <>
Date:   Tue Dec 1 09:37:07 2020 +0100

    Cygwin: /proc/sys FS: don't export NFS and DFS as block devices
    Network filesystems are not block devices.  Apparently this code
    hasn't been executed anyway, given how network filesystems are
    hidden behind \Device\Mup.
