[PATCH v1 00/19] NFS/RDMA client patches for next

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Anna-

Don't know what to call the next kernel release. v4.18? v5.0?
Anyway, here is the full set I'd like to see merged in that
release.

Along with the Receive efficiency-related patches that did not
get into v4.17, there are a number of unrelated fixes, improve-
ments, and clean ups in this series.

There is a three-patch series near the end that handles the
"empty sendctx queue" case a little more nicely. Instead of
waiting an arbitrary amount of time and trying again, an RPC
waits for the transport to wake it up when there are more
sendctxs available. I've found this makes the transport a
little less prone to deadlock under heavy workloads.

As usual, the series can be found in my git repo as well:
