Summary     : The process which starts the flushing of dirty buffers back to disk.
Description :
The bdflush process starts the kernel daemon which flushes dirty
buffers back to disk (i.e., writes all unwritten data to disk).
This helps to prevent the buffers from growing too stale.

Bdflush is a basic system process that must run for your system
to operate properly.
