Hi all, After merging the ext3 tree, today's linux-next build (x86_64 allmodconfig) failed like this: In file included from include/linux/sysctl.h:27, from include/linux/fanotify.h:5, from fs/notify/fanotify/fanotify.c:2: fs/notify/fanotify/fanotify.c: In function 'fanotify_get_response': fs/notify/fanotify/fanotify.c:233:48: error: suggest parentheses around arithmetic in operand of '|' [-Werror=parentheses] 233 | TASK_KILLABLE|TASK_FREEZABLE); | ^ include/linux/wait.h:283:11: note: in definition of macro '___wait_is_interruptible' 283 | (state & (TASK_INTERRUPTIBLE | TASK_WAKEKILL))) | ^~~~~ include/linux/wait.h:935:9: note: in expansion of macro '___wait_event' 935 | ___wait_event(wq, condition, state, 0, 0, schedule()) | ^~~~~~~~~~~~~ include/linux/wait.h:958:25: note: in expansion of macro '__wait_event_state' 958 | __ret = __wait_event_state(wq_head, condition, state); \ | ^~~~~~~~~~~~~~~~~~ fs/notify/fanotify/fanotify.c:231:15: note: in expansion of macro 'wait_event_state' 231 | ret = wait_event_state(group->fanotify_data.access_waitq, | ^~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors Caused by commit 3440e7e55ced ("fanotify: allow freeze when waiting response for permission events") Though, I guess, you could argue that the ___wait_is_interruptible macro should parenthesise the use of its "state" argument. I have used the ext3 tree from next-20240306 for today. -- Cheers, Stephen Rothwell
