From e31d802479df9daff1994a7ed1e36bbc5bb19d03 Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Thu, 29 Nov 2018 20:32:30 -0600 Subject: [PATCH] nbd/server: Advertise all contexts in response to bare LIST The NBD spec, and even our code comment, says that if the client asks for NBD_OPT_LIST_META_CONTEXT with 0 queries, then we should reply with (a possibly-compressed representation of) ALL contexts that we are willing to let them try. But commit 3d068aff forgot to advertise qemu:dirty-bitmap:FOO.
