Lawrence Livermore National Labs recently ran the source code
analysis tool Coverity over the e2fsprogs-1.39 source to see
if it would identify any significant bugs. The analysis
turned up 38 mostly minor issues which are enumerated here
with patches. We went through and resolved these issues
but would love to see these mostly minor changes reviewed
and commited upstream.
Thanks,
Brian Behlendorf <[email protected]>, and

Coverity ID: 37: Resource Leak
The memory allocated by block_buf is not reclaimed. At this point
block_buf has not even really been used at all. Should be safe
to free it.
