Ensure we update the 'partitionSize' field of the component labels

Return error in the case of using ODIOCGDINFO or ODIOCGDEFLABEL when

For the RF_ASSERT() and RF_PANIC() macros, call a function to do the

rationalize the use of b_flags for geteblk() buffers.

In the event that an up-to-date component cannot be located for a specific

Components which match on everything but the mod_counter are

renegades, and must be handled correctly. In particular, they should

Failing to do otherwise means that they potentialy end up in a

of the correct one, and cause all sorts of chaos at auto-configure
time.
