[PATCH btt] 2/6 - Changed adding INSERT traces to the IO tree, instead using GETRQ traces.

[Alan D. Brunelle]

Changed triggering on INSERT to GETRQ (temporary?)

From:  Alan D. Brunelle <[EMAIL PROTECTED]>
Signed-off-by: Alan D. Brunelle <[EMAIL PROTECTED]

This is backwards compatible with previous versions, with the one
difference being that the Q2I information may be a bit shorter. 

The changes forthcoming with the explicit unplugging (2.6.20 + Jens'
unplag patches) require this. We may need to redefine and/or add a new
measurement once that settles down. When that happens, we'll most likely be
renaming things to better reflect GETRQ versus INSERT.
