[PATCH 0/2] revert 9pfs reply truncation, wait for free room to reply

[Stefano Stabellini]

Hi all,

This short series reverts commit 16724a173049ac29c7b5ade741da93a0f46edff
becauses it is the cause for https://bugs.launchpad.net/bugs/1877688.

The original issue addressed by 16724a173049ac29c7b5ade741da93a0f46edff
is solved differently in this series by using qemu_coroutine_yield() to
wait for the client to free more data from the ring before sending the
reply.

Cheers,

Stefano
