[PATCH] libpager's stub functions doesn't update seqno

From: Sergio Lopez
Subject: [PATCH] libpager's stub functions doesn't update seqno
Date: Wed, 10 Aug 2005 17:33:37 +0200


Hurd's libpager library makes use of the port's sequence number (seqno) to
serialize requests. The stub functions (stubs.c notify-stubs.c) doesn't
properly update this number, so when they are called (pretty unusual,
but it happens on some special situations, i.e. when GNU Mach tries to
access a pager with the ports previously unallocated by
object-terminate.c) the next request is waiting forever in

Changelog entry:
