Subject: rcu warnings in tun
Date: Thu, 30 Jul 2020 16:16:17 -0400 [thread overview]
Message-ID: <20200730161536-mutt-send-email-mst@kernel.org> (raw)
Was building tun with sparse the other day, noticed this:
drivers/net/tun.c:3003:36: warning: incorrect type in argument 2 (different address spaces)
drivers/net/tun.c:3003:36: expected struct tun_prog [noderef] __rcu **prog_p
drivers/net/tun.c:3003:36: got struct tun_prog **prog_p
drivers/net/tun.c:3292:42: warning: incorrect type in argument 2 (different address spaces)
drivers/net/tun.c:3292:42: expected struct tun_prog **prog_p
drivers/net/tun.c:3292:42: got struct tun_prog [noderef] __rcu **
drivers/net/tun.c:3296:42: warning: incorrect type in argument 2 (different address spaces)
drivers/net/tun.c:3296:42: expected struct tun_prog **prog_p
drivers/net/tun.c:3296:42: got struct tun_prog [noderef] __rcu **
any idea when did these surface?
