mac80211: mesh: use hlist for rmc cache The RMC cache has 256 list heads plus a u32, which puts it at the unfortunate size of 4104 bytes with padding. kmalloc() will then round this up to the next power-of-two, so we wind up actually using two pages here where most of the second is wasted. Switch to hlist heads here to reduce the structure size down to fit within a page. Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
