mm/vmalloc: revert "mm/vmalloc.c: check VM_UNINITIALIZED flag in s_show instead of show_numa_info"
The VM_UNINITIALIZED/VM_UNLIST flag introduced by f5252e009d5b ("mm: avoid null pointer access in vm_struct via /proc/vmallocinfo") is used to avoid accessing the pages field with unallocated page when show_numa_info() is called. This patch moves the check just before show_numa_info in order that some messages still can be dumped via /proc/vmallocinfo. This patch reverts commit d157a55815ff ("mm/vmalloc.c: check VM_UNINITIALIZED flag in s_show instead of show_numa_info"); Reviewed-by: Zhang Yanfei <zhangyanfei@cn.fujitsu.com> Signed-off-by: Wanpeng Li <liwanp@linux.vnet.ibm.com> Cc: Mitsuo Hayasaka <mitsuo.hayasaka.hu@hitachi.com> Cc: Joonsoo Kim <iamjoonsoo.kim@lge.com> Cc: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Cc: David Rientjes <rientjes@google.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
