[PATCH] mark several libata datastructures const
Hi, the patch below marks several libata (and libata-driver) structures const so that they end up in the .rodata segment and don't false-share cachelines with things that get dirtied often. Signed-off-by: Arjan van de Ven <arjan@infradead.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
