[PATCH net v2 14/15] mptcp: being below memory limit is a likely() condition
From: "Matthieu Baerts (NGI0)" <matttbe@kernel.org>
Date: 2026-09-08 14:14:52
Also in:
lkml, mptcp, stable
Subsystem:
networking [general], networking [mptcp], the rest · Maintainers:
"David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Matthieu Baerts, Mat Martineau, Linus Torvalds
From: Paolo Abeni <pabeni@redhat.com>
The current compiler hint annotation is wrong, due to inverted
logic in the previous revision of the relevant code.
Fixes: e468d371180d ("mptcp: implemented OoO queue pruning")
