| |
Hi all,
After merging the percpu tree, today's linux-next build (arm multi_v7_defconfig) produced this warning:
In file included from include/linux/kernel.h:13:0, from include/linux/bitmap.h:9, from mm/percpu.c:58: mm/percpu.c: In function 'pcpu_alloc': include/linux/printk.h:303:2: warning: 'err' may be used uninitialized in this function [-Wmaybe-uninitialized] printk(KERN_WARNING pr_fmt(fmt), ##__VA_ARGS__) ^ mm/percpu.c:864:14: note: 'err' was declared here const char *err; ^
I am not sure which commit introduced this, although the
if (is_atomic) goto fail;
in pcpu_alloc() looks suspicious.
-- Cheers, Stephen Rothwell
