Subject: [PATCH v4 net-next 0/3] bonding: fix bond_3ad RCU usage
Date: Fri, 10 Jan 2014 11:59:42 +0100 [thread overview]
Message-ID: <1389351585-19615-1-git-send-email-vfalico@redhat.com> (raw)
While digging through bond_3ad.c I've found that the RCU usage there is
just wrong - it's used as a kind of mutex/spinlock instead of RCU.
v3->v4: remove useless goto and wrap __get_first_agg() in proper RCU.
v2->v3: make bond_3ad_set_carrier() use RCU read lock for the whole
function, so that all other functions will be protected by RCU as well.
This way we can use _rcu variants everywhere.
v1->v2: use generic primitives instead of _rcu ones cause we can hold RTNL
lock without RCU one, which is still safe.
This patchset is on top of bond_3ad.c cleanup:
