From: Julia Lawall <[EMAIL PROTECTED]> Robert P.J. Day proposed to use the macro FIELD_SIZEOF in replace of code that matches its definition.
The modification was made using the following semantic patch (http://www.emn.fr/x-info/coccinelle/) // <smpl> @haskernel@ @@ #include <linux/kernel.h> @depends on haskernel@ type t; identifier f; @@ - (sizeof(((t*)0)->f)) + FIELD_SIZEOF(t, f) @depends on haskernel@ type t; identifier f; @@ - sizeof(((t*)0)->f) + FIELD_SIZEOF(t, f) // </smpl> Signed-off-by: Julia Lawall <[EMAIL PROTECTED]> Cc: Jens Axboe <[EMAIL PROTECTED]> Cc: Benjamin Herrenschmidt <[EMAIL PROTECTED]> Cc: Paul Mackerras <[EMAIL PROTECTED]> Acked-by: Stephen Rothwell <[EMAIL PROTECTED]> Signed-off-by: Andrew Morton <[EMAIL PROTECTED]> --- drivers/block/viodasd.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff -puN drivers/block/viodasd.c~drivers-block-viodasdc-use-field_sizeof drivers/block/viodasd.c --- a/drivers/block/viodasd.c~drivers-block-viodasdc-use-field_sizeof +++ a/drivers/block/viodasd.c @@ -69,7 +69,7 @@ MODULE_LICENSE("GPL"); enum { PARTITION_SHIFT = 3, MAX_DISKNO = HVMAXARCHITECTEDVIRTUALDISKS, - MAX_DISK_NAME = sizeof(((struct gendisk *)0)->disk_name) + MAX_DISK_NAME = FIELD_SIZEOF(struct gendisk, disk_name) }; static DEFINE_SPINLOCK(viodasd_spinlock); _ _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
