selinux: Add a cache for quicker retreival of PKey SIDs It is likely that the SID for the same PKey will be requested many times. To reduce the time to modify QPs and process MADs use a cache to store PKey SIDs. This code is heavily based on the "netif" and "netport" concept originally developed by James Morris <jmorris@redhat.com> and Paul Moore <paul@paul-moore.com> (see security/selinux/netif.c and security/selinux/netport.c for more information) Signed-off-by: Daniel Jurgens <danielj@mellanox.com> Acked-by: Doug Ledford <dledford@redhat.com> Signed-off-by: Paul Moore <paul@paul-moore.com> 2017-05-19 20:48:59 +08:00			`/*`
