Subject: [Qemu-devel] [PATCH v9 0/3] NBD reconnect
Date: Tue, 17 Sep 2019 20:13:19 +0300 [thread overview]
Message-ID: <20190917171322.4127-1-vsementsov@virtuozzo.com> (raw)
Hi all!
Here is NBD reconnect. Previously, if connection failed all current
and future requests will fail. After the series, nbd-client driver
will try to reconnect unlimited times. During first @reconnect-delay
seconds of reconnecting all requests will wait for the connection,
and if it is established requests will be resent. After
@reconnect-delay period all requests will be failed (until successful
reconnect).
v9:
01: - fix grammar [Eric] [1]
- add "static" to qemu_co_sleep_ns__scheduled variable definition [Eric] [2]
- add public typedef for internal QemuCoSleepState and use it [Kevin]
[this leads to returning of co_sleep_cb, as we need wrapper with
void * argument o pass to aio_timer_new][3]
- rename function and add helper with old name and old semantics [Kevin]
- keep Kevin's r-b, hope [1], [2] and [3] are not too much.
02: rebase on 01 changes
some tiny improvements from Eric's review
