Description Amar Tumballi 2012-03-10 14:33:50 UTC

Description of problem:
iobuf_get2(); can return NULL if the sizes requested are higher than the available ones. Currently, even though there is a log to see that failures are happening, there is no counter about how many requests are getting failed. This counter can help to see for a given workload, what are the higher sizes required for iobuf.

Version-Release number of selected component (if applicable): Master branch
