H A D | super.c | c071fcfd Fri Jan 16 10:59:08 CST 2009 Chris Mason <chris.mason@oracle.com> Btrfs: fix ioctl arg size (userland incompatible change!)
The structure used to send device in btrfs ioctl calls was not properly aligned, and so 32 bit ioctls would not work properly on 64 bit kernels.
We could fix this with compat ioctls, but we're just one byte away and it doesn't make sense at this stage to carry about the compat ioctls forever at this stage in the project.
This patch brings the ioctl arg up to an evenly aligned 4k.
