When content of an object is modified from filesystem interface, a GET
on the object will return inconsistent or incomplete content because the
content length originally stored as metadata no longer reflects the
actual length of the file after modification.
The complete fix will have two parts:
(1) Return the entire content of object as is to the client
(2) The Etag returned should reflect the actual md5sum of object content
This change only fixes (1) mentioned above. This means, the client will
always get the complete content of the file.
Fix (2) is not part of this change. This means, if content length of the
object remains same even after modification, the Etag returned would be
incorrect. Fixing (2) involves more invasive changes in the code. So
that is deferred for now and will be sent as a separate change later.
