Subject: [PATCH v2 0/3] revert 9pfs reply truncation, wait for free room to reply
Date: Thu, 21 May 2020 12:26:18 -0700 (PDT) [thread overview]
Message-ID: <alpine.DEB.2.21.2005211225030.27502@sstabellini-ThinkPad-T480s> (raw)
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
Changes in v2:
- add comments on barriers
- add patch to increase ring size to the max allowed
