Hi there,
a few months ago I noticed that nbd-client (kmod code actually) randomly
shuts down the connection during heavy parallel xdd benchmarks in my
local setup. The following change to nbd.c fixed that for me:
@@ -303,9 +303,13 @@
struct request *req, *tmp;
int err;
+wait:
err = wait_event_interruptible(nbd->active_wq, nbd->active_req != xreq);
- if (unlikely(err))
+ if (unlikely(err)) {
+ if (err == -ERESTARTSYS)
+ goto wait;
goto out;
+ }
Please consider pushing it upstream.
Thanks!
