Subject: at_wini: removed RO_BIT misfeature, not used any more
X-Git-Tag: v3.1.2a~250
X-Git-Url: http://zhaoyanbai.com/repos/dnssec-verify.html?a=commitdiff_plain;h=1a7f7d63338a274a1494fcbb0f90a8f98fdfa054;p=minix.git

at_wini: removed RO_BIT misfeature, not used any more
pm: fixed rebooting by making a copy of the monitor code from the user
    process. this is necessary because that process is dead by the time
    sys_abort() is called.

    also added more info to the "can't reply" panic.
