[ofa-general] Registration of Shared memory with read only permission fails

[Dotan Barak]

Hi.

I allocated a shared memory with read only permission and tried to 
register it
(as read only memory) and failed.
(in the kernel level: drivers/infiniband/core/umem.c, function 
get_user_pages failed)

Attached is a short code that reproduces this error.

Is this is an expected behavior?

thanks
Dotan
