Mark, any chance to try it?  Just create an XFS filesystem, age it a
bit and then call the attached little trim.c program on the mountmoint
(or any file inside the filesystem for that matter)

..

Looking at it now.  Thanks, Christoph!

..

Fails to work on 64-bit kernel w/ 32-bit userspace (no compat ioctl).
Rebuilding with 32-bit kernel now..

The actual ioctl is compatible, just add the

	case XFS_IOC_TRIM:
		return xfs_ioc_trim(mp, arg);

to xfs_file_compat_ioctl().  I'll add this to the next spin of the patch.

..

Peachy.  Rebuilding again now..

Don't wait up for this .. I'll finish it on Sunday.  Bedtime.  :)
