Subject: [PATCH v3 net-next 00/13] net: complete dev_base_lock removal
Back in 2009 we started an effort to get rid of dev_base_lock
in favor of RCU.
It is time to finish this work.
Say goodbye to dev_base_lock !
v3: I misread kbot reports, the issue was with dev->operstate (patch 10/13)
So dev->reg_state is back to u8, and dev->operstate becomes an u32.
Sorry for the noise.
v2: dev->reg_state must be a standard enum, some arches
do not support cmpxchg() on u8.
Eric Dumazet (13):
net: annotate data-races around dev->name_assign_type
ip_tunnel: annotate data-races around t->parms.link
dev: annotate accesses to dev->link
net: convert dev->reg_state to u8
net-sysfs: convert netdev_show() to RCU
net-sysfs: use dev_addr_sem to remove races in address_show()
net-sysfs: convert dev->operstate reads to lockless ones
net-sysfs: convert netstat_show() to RCU
net: remove stale mentions of dev_base_lock in comments
net: add netdev_set_operstate() helper
net: remove dev_base_lock from do_setlink()
net: remove dev_base_lock from register_netdevice() and friends.
net: remove dev_base_lock
