[openib-general] Fork issues with simple MPI program

[Davis, Arlin R]

>An application that wants fork() to work with libibverbs should
>either call ibv_fork_init() before doing anything else with
>libibverbs, or else a user can set the IBV_FORK_SAFE or
>RDMAV_FORK_SAFE environment variable to get the same effect.  There is
>some overhead to making fork() work so it is not enabled by default.
>This is described in the ibv_fork_init manpage in the latest
>libibverbs git tree.


Does this require 2.6.16 or better kernel support?
