[PATCH v1 0/2] xen: mapcache: Fix unmapping of first the entry in a bucket

Posted by Edgar E. Iglesias 2 months, 1 week ago

From: "Edgar E. Iglesias" <edgar.iglesias@amd.com>

This fixes the unmapping of the first mapping in a bucket of a mapcache.

We also add error handling to qemu_ram_block_from_host() to bail out when
xen_ram_addr_from_mapcache() doesn't find an existing mapping.

Cheers,
Edgar
