Branch b_release_1_6_5
Description: MDS may lose file striping (and hence file data) in some cases
Details    : If there are additional extended attributes stored on the MDS,
           in particular ACLs, SELinux, or user attributes (if user_xattr
           is specified for the client mount options) then there is a risk
           of attribute loss.  Additionally, the Lustre file striping
           needs to be larger than default (e.g. striped over all OSTs),
           and an additional attribute must be stored initially in the
           inode and then increase in size enough to be moved to the
           external attribute block (e.g. ACL growing in size) for file
           data to be lost.
