Remove extra pserialize_perform from in_purgeaddr
It's already performed in ifa_remove. Note so there (in in6_unlink_ifa too).
Release rt_so_mtx on updating a rtentry to avoid a deadlock with route_intr
The deadlock happened only if NET_MPSAFE on.
Run tcp_slowtimo in workqueue if NET_MPSAFE
If NET_MPSAFE is enabled, we have to avoid taking softnet_lock in softint as
much as possible to prevent any softint handlers including callout handlers
such as tcp_slowtimo from sticking on softnet_lock because it results in
undesired delays of executing subsequent softint handlers.
NFCI for !NET_MPSAFE
Fix a return value of rt_update_prepare
Callers expect it to be an errno.
Fix another deadlock
When waiting for a route update to finish, a waiter has to release its reference
to the route to avoid a deadlock. Because a updater tries to wait for references
to a target route (except for a reference by the updater itself) to be released.
