It was originally written by me at Red Hat (thus the "From: Steven Rostedt (Red Hat)"), and that signed-off-by is from Red Hat Steven. Then Tzvetomir ported it over to libtraceveent in the kernel tree, which requires his signed-off-by, and then I pull Tzvetomir's work and the VMware Steven Rostedt signed it off. ;-) As Signed-off-by does have some legal meaning for "right to use this code" I feel it's more than prudent to include both the Red Hat Steven's signed-off-by as well as the VMware Steven's signed-off-by. Make sense? -- Steve
