>Description:
Upgrading 7.1-PRERELEASE to 7.2-Stable
Building Generic Kernel reports error
/usr/src/sys/dev/ata/ata-all.c: In function 'ata_device_ioctl':
/usr/src/sys/dev/ata/ata-all.c:454: error: request for member 'max_iosize' in something not a structure or union
/usr/src/sys/dev/ata/ata-all.c:454: error: request for member 'max_iosize' in something not a structure or union

/usr/src/sys/dev/ata/ata-all.c:454 reads

           (ch->dma.max_iosize ? ch->dma.max_iosize : DFLTPHYS)) {

dma is a pointer in struct ata_channel see Fix: for probable code change required

__FBSDID("$FreeBSD: src/sys/dev/ata/ata-all.c,v 1.280.2.9 2009/07/30 13:19:12 mav Exp $");

>How-To-Repeat:
Build 7.2-Stable Kernel pre 31 Jul 2009

edit /usr/src/sys/dev/ata/ata-all.c:454 to read

          (ch->dma ? ch->dma->max_iosize : DFLTPHYS)) {
