rio/everywhere: add icreate/namelink fop
icreate creates inode, while namelink links the basename to it's parent gfid. For now mkdir is the primary user of these fops. Better distribution is acheived by creating the inode on ,(say) mds1 and linking the basename to it's parent gfid on mds2. The inode serves readdirp, stat etc. More details about the fops are present at: https://review.gluster.org/#/c/13395/3/design/DHT2/DHT2_Icreate_Namelink_Notes.md This backport of three patches from experimental branch. 1- https://review.gluster.org/#/c/18085/ 2- https://review.gluster.org/#/c/18086/ 3- https://review.gluster.org/#/c/18094/ Updates gluster/glusterfs#243 Change-Id: I1bd3d5a441a3cfab1acfeb52f15c6c867d362592 Signed-off-by: Susant Palai <spalai@redhat.com>
