[Xen-devel] [PATCH v3 2/2] xen: make CONFIG_DEBUG_LOCKS usable without CONFIG_DEBUG

[Juergen Gross <jgross@xxxxxxxx>]

In expert mode it is possible to enable CONFIG_DEBUG_LOCKS without
having enabled CONFIG_DEBUG. The coding is depending on CONFIG_DEBUG
as it is using ASSERT(), however.

Fix that by using BUG_ON() instead of ASSERT() in rel_lock().
