Florian Fainelli 9fb20801da net: Fix ip_mc_{dec,inc}_group allocation context ... After 4effd28c12 ("bridge: join all-snoopers multicast address"), I started seeing the following sleep in atomic warnings: [ 26.763893] BUG: sleeping function called from invalid context at mm/slab.h:421 [ 26.771425] in_atomic(): 1, irqs_disabled(): 0, pid: 1658, name: sh [ 26.777855] INFO: lockdep is turned off.

Pass a gfp_t down to igmpv3_add_delrec(), introduce __igmp_group_dropped() and introduce __ip_mc_dec_group() to take a gfp_t argument. Similarly introduce ____ip_mc_inc_group() and __ip_mc_inc_group() to allow caller to specify gfp_t. IPv6 part of the patch appears fine.
