> Patch 2 fixes behaviour under pressure, retrying inserts in non-permanent
>         error case (-EBUSY).
> Patch 3 auto-adjusts the upper table size limit according to the number
>         of threads (in concurrency test). In fact, the current default is
> 	already too small.
> Patch 4 makes it possible to retry inserts even in supposedly permanent
>         error case (-ENOMEM) to expose rhashtable's remaining problem of
> 	-ENOMEM being not as permanent as it is expected to be.

> Changes since v1:

>   well.
> - Do not retry inserts by default if -ENOMEM was returned.
> - Rename the retry counter to be a bit more verbose about what it
>   contains.
> - Add patch 4 as a debugging aid.

Series applied, thanks Phil.
