Subject: memory: check address space when a listener is registered
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=221b3a3f1e5edb9e41a48bfa384803800184b397;p=qemu.git

memory: check address space when a listener is registered

This patch resolves a bug in memory listener registration.
"range_add" callback  was called on each section of the both
address space (IO and memory space) even if it doesn't match
the address space filter.
