Is it possible that desc_table ever happens to NULL? It looks
like a test something else was intended here ?
It is a defensive check. yes can never be true and can be removed
Sasi
Also all the VD_EXT_DEBUG macros make with bad indentation added
make the code hard to read. Please fix it later in a follow up patch.
Sasi - This shall be fixed in V5 patch
