IB/ipath: Make send buffers available for kernel if not allocated to user
A fixed partitioning of send buffers is determined at driver load time for user processes and kernel use. Since send buffers are a scarce resource, it makes sense to allow the kernel to use the buffers if they are not in use by a user process. Also, eliminate code duplication for ipath_force_pio_avail_update(). Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
