2017-02-06T15:38:07+00:00

To enable the integration of md-cache and invalidation features

In order to ease this for user provide a group volume set option.

Usage: gluster vol set  group metadata-cache

Backport of http://review.gluster.org/16296

From kernel version 3.X or greater, creating of a file
results in removexattr call on security.ima xattr. But
this xattr is not set on the file unless IMA feature
is active. With this patch, removxattr call returns
ENODATA if it is not found in the cache.
