Hi Al, After merging the vfs tree, today's linux-next build (powerpc ppc64_defconfig) produced this warning: kernel/events/core.c: In function 'perf_ioctl': kernel/events/core.c:3285:17: warning: 'output.file' may be used uninitialized in this function [-Wuninitialized] include/linux/file.h:36:5: warning: '*((void *)&output+8)' may be used uninitialized in this function [-Wuninitialized] kernel/events/core.c:3281:14: note: '*((void *)&output+8)' was declared here Introduced by commit 19ba95358327 ("switch simple cases of fget_light to fdget"). perf_fget_light() takes the address of a struct fd * but does not do anything with it ... -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
