[Qemu-devel] [PATCH 1/3] nbd/server: Advertise all contexts in response to bare LIST |
Date: |
Thu, 29 Nov 2018 20:32:30 -0600 |
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.
