Add __acquires() and __releases() annotations to suppress some sparse warnings. example of warnings : net/ipv4/udp.c:1555:14: warning: context imbalance in 'udp_seq_start' - wrong count at exit net/ipv4/udp.c:1571:13: warning: context imbalance in 'udp_seq_stop' - unexpected unlock Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.
