Merge branch 'a-few-corrections-for-sock_support_zc'
Pavel Begunkov says:
====================
a few corrections for SOCK_SUPPORT_ZC
There are several places/cases that got overlooked in regards to
SOCK_SUPPORT_ZC. We're lacking the flag for IPv6 UDP sockets and
accepted TCP sockets. We also should clear the flag when someone
tries to hijack a socket by replacing the ->sk_prot callbacks.
