From e1dc1c78e7a523fc64ca28bed60a9a40ea1de46a Mon Sep 17 00:00:00 2001 From: Zach Koopmans Date: Tue, 22 Jun 2021 15:50:41 -0700 Subject: [syserror] Add conversions to linuxerr with temporary Equals method. Add Equals method to compare syserror and unix.Errno errors to linuxerr errors. This will facilitate removal of syserror definitions in a followup, and finding needed conversions from unix.Errno to linuxerr.
