If you prefer to fix _two_ problems in one patch, sure.

For the record, the bug this patch fixes is NOT same with the one
in rds_find_bound(), because there is no rds_find_bound() in
the backtrace. If you want to see the full backtrace, here it is:

https://marc.info/?l=linux-netdev&m=153644444808962&w=2

This is why I believe they are two problems.

Whether fixing two problems in one patch or two patches is
merely a preference, I leave it up to you.
