[PATCH net-next 06/14] rxrpc: Purge the to_be_accepted queue on socket release

From: David Howells
Date: Sat Sep 17 2016 - 19:18:35 EST


Purge the queue of to_be_accepted calls on socket release. Note that
purging sock_calls doesn't release the ref owned by to_be_accepted.

Probably the sock_calls list is redundant given a purges of the recvmsg_q,
the to_be_accepted queue and the calls tree.
