Hi all, After merging the tip tree, today's linux-next build (arm multi_v7_defconfig) produced this warning: kernel/futex.c: In function 'do_futex': kernel/futex.c:1676:17: warning: 'oldval' may be used uninitialized in this function [-Wmaybe-uninitialized] 1676 | return oldval == cmparg; | ~~~~~~~^~~~~~~~~ kernel/futex.c:1652:6: note: 'oldval' was declared here 1652 | int oldval, ret; | ^~~~~~ Introduced by commit a08971e9488d ("futex: arch_futex_atomic_op_inuser() calling conventions change") but I don't see how it makes this difference :-( -- Cheers, Stephen Rothwell
