What you're looking for is a filesystem-specific feature and can be
utilized using the O_DIRECT flag in the open(2) system call. If
you're filesystem does not support raw i/o EINVAL is returned. Since
I am using XFS I can't tell you about other fs, but I suppose Ext2,
Ext3 and JFS do support it. (Corrections welcome.)
