Willem de Bruijn 14ade6ba41 net: msg_zerocopy: elide page accounting if RLIM_INFINITY ... MSG_ZEROCOPY ensures that pinned user pages do not exceed the limit. If no limit is set, skip this accounting as otherwise expensive atomic_long operations are called for no reason. This accounting is already skipped for privileged (CAP_IPC_LOCK) users. Rely on the same mechanism: if no mmp->user is set, mm_unaccount_pinned_pages does not decrement either. Tested by running tools/testing/selftests/net/msg_zerocopy.sh with an unprivileged user for the TXMODE binary: ip netns exec "${NS1}" sudo -u "{$USER}" "${BIN}" "-${IP}" ...
