I've done the latter in the latest patchset. Since mpol_equal() is only used for determining whether nearby vmas can be merged, it is only logical to merge them if they share the mempolicy intent of the user if MPOL_F_STATIC_NODES or any flag that makes sense of policy->user_nodemask is used. > > Could we have mpol_to_str() mark policies which are > > MPOL_F_RELATIVE_NODES or MPOL_F_STATIC_NODES?

This is also how tmpfs mount options will be specified. [ Of course the above example can't happen since MPOL_F_STATIC_NODES and MPOL_F_RELATIVE_NODES are disjoint, but it's sufficient for the example. ] -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
