From 8a335a2331c72e60c6b3ef09b2dedd3ba00da1b1 Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Mon, 9 Mar 2009 16:31:04 +0800 Subject: ACPICA: Fix AcpiWalkNamespace race condition with table unload Added a reader/writer locking mechanism to allow multiple concurrent namespace walks (readers), but a dynamic table unload will have exclusive access to the namespace. This fixes a problem where a table unload could delete the portion of the namespace that is currently being examined by a walk. Adds a new file, utlock.c that implements the reader/writer lock mechanism.
