From c4512c63b1193c73b3f09c598a6d0a7f88da1dd8 Mon Sep 17 00:00:00 2001 From: Matthieu Baerts Date: Fri, 25 Jun 2021 14:25:22 -0700 Subject: mptcp: fix 'masking a bool' warning Dan Carpenter reported an issue introduced in commit fde56eea01f9 ("mptcp: refine mptcp_cleanup_rbuf") where a new boolean (ack_pending) is masked with 0x9. This is not the intention to ignore values by using a boolean. This variable should not have a 'bool' type: we should keep the 'u8' to allow this comparison.
