Doc Text:	.Fixed a memory leak with the Ceph Object Gateway A buffer used to transfer incoming PUT data was incorrectly sized at the maximum chunk value of 4 MB. This was leading to a space leak of unused buffer space when PUTs of smaller objects were processed. The Ceph Object Gateway can leak space when processing large numbers of PUT requests less than 4M in size. As a result, the incorrect buffer sizing logic was fixed.	Story Points:	---
