Author: imp Date: Fri Aug 28 17:49:56 2020 New Revision: 364925 URL: https://svnweb.freebsd.org/changeset/base/364925 Log: Allow the pseudo-errnos to be returned as well in boot loader Expose the pseudo-errno values in _STANDALONE is defined so that code in the boot loader can make use of them. Nothing uses them today, but the zstd support that's coming will need them.
