Hi Malahal,
They are nfs_ganesha_iozone_vfs and nfs_ganesha_iozone_vfs_minmdcache.
For every patch submission they build ganesha with the patch, set up the server that was just built with a FSAL_VFS, and run the iozone workload on the client. nfs_ganesha_iozone_vfs uses the default config, and nfs_ganesha_iozone_vfs_minmdcache uses the settings you requested.
(Note: the regular nfs_ganesha_iozone uses FSAL_GLUSTER. Most of the tests use FSAL_GLUSTER as they were written by the gluster team for nfs-ganesha+gluster.)
Let me know if you have any questions.
Regards,
