[9fans] odd rwakeup qunlock behaviour in 9vx
I have a function chan_send in which :
chan_send (...) {
qlock()
rwakeup(...)
qunlock()
}
If two such chan_send functions are called without a "task-switch" 9vx crashes.
A work around for this problem is to place a sleep(0) after qunlock to enforce
a task-switch
chan_send(...) {
qlock()
rwakeup(...)
qunlock()
sleep(0)
}
This behaviour isn't documented anywhere. I'll test it next on bare metal with
a real kernel to find out if this is only a 9vx problem.

That last message was me, not anything official.

Pings (v4 and 6) to nearby addresses work, so it looks like the host itself is down. -- 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T1250ef82fbb8d6ed-Mbf332bb9fb0f83f30583f883 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
