Pretty much every 32-on-64 combination was broken, and some archs (like mips, both endians) use 32-on-64 on all non-museal hardware. I've tested that your patch fixes at least: * x32 on amd64 * armhf on arm64 So big thanks for this fix! There are other broken ioctls, for example: /mnt/vol1/b: fiemap error 25: Inappropriate ioctl for device /mnt/vol1/a: fiemap error 25: Inappropriate ioctl for device but the last I checked, fiemap doesn't live in fs/btrfs/ Meow! -- Autotools hint: to do a zx-spectrum build on a pdp11 host, type: ./configure --host=zx-spectrum --build=pdp11 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
