MINOR: fd: move a few read-mostly variables to their own section Some pointer to arrays such as fdtab, fdinfo, polled_mask etc are never written to at run time but are used a lot. fdtab accesses appear a lot in perf top because ha_used_fds is in the same cache line and is modified all the time. This patch moves all these read-mostly variables to the read_mostly section when defined. This way their cache lines will be able to remain in shared state in all CPU caches.
