2021-06-16[syserror] Refactor linuxerr and error package.Zach Koopmans
Move Error struct to pkg/errors package for use in multiple places. Move linuxerr static definitions under pkg/errors/linuxerr. Add a lookup list for quick lookup of *errors.Error by errno. This is useful when converting syserror errors and unix.Errno/syscall.Errrno values to *errors.Error. Update benchmarks routines to include conversions. The below benchmarks show *errors.Error usage to be comparable to using unix.Errno.

2021-05-18[syserror] Add linuxerr package.Zach Koopmans
Add linuxerr package to replace syserror and syserr errors. This is done to improve performance comparing/returning errors to on par with syscall.Errno. The below linuxerr_test (formerly syserror_test) shows linuxerr.Error on par with unix.Error (syscall.Errno) as desired.
