On 32-bit architectures with KASAN_STACK enabled, the total stack usage of the ocfs2_ioctl function grows beyond the warning limit: fs/ocfs2/ioctl.c: In function 'ocfs2_ioctl': fs/ocfs2/ioctl.c:934:1: error: the frame size of 1448 bytes is larger than 1400 bytes [-Werror=frame-larger-than=] Move each of the variables into a basic block, and mark ocfs2_info_handle() as noinline_for_stack, in order to have the variable share stack slots.
