performance/write-behind: fix data corruption while aggregating the adjacent contiguous iobufs into a single iobuf

2010-02-23T07:27:06+00:00

- while aggregating, we should make sure that the destination has enough
   memory. __wb_collapse_write_bufs assumed that destination vector's iov_base
   was aligned to the start of an iobuf and hence memory of page_size is
   available for aggregation. This assumption is not always true, like in the
   configuration consisting afr->write->io-cache (afr is on top). Refer to the
   bug url for more details.
