Bug ID: 1523094
Summary: to detect EOF, avoid sending readv fop to backend when
offset is within byte range of file size
Product: GlusterFS
Version: mainline
Component: quick-read
Assignee: bugs at gluster.org
Reporter: mchangir at redhat.com
CC: bugs at gluster.org
Description of problem:
currently, a readv fop is forwarded to brick backend to detect EOF
Expected results:
with quick-read turned "on" and the file contents cached, the EOF detection
should take place at the client end and should not be incur a network hop to
the back-end file system.
