Here are all the ops that need to be supported through MDCACHE, I am not
sure it it is the way of any call-backs.
Thabks, Marc.
static void dsh_ops_init(struct fsal_dsh_ops *ops)
{
/* redundant copy, but you never know about the future... */
memcpy(ops, &def_dsh_ops, sizeof(struct fsal_dsh_ops));
ops->release = ds_release;
ops->read = ds_read;
ops->read_plus = ds_read_plus;
ops->write = ds_write;
ops->write_plus = ds_write_plus;
ops->commit = ds_commit;
}
/**
* @brief set ops layout
*
* @param ops reference to object
*/
void handle_ops_pnfs(struct fsal_obj_ops *ops)
{
ops->layoutget = layoutget;
ops->layoutreturn = layoutreturn;
ops->layoutcommit = layoutcommit;
}

I'll go through and make sure that all ops that are stackable are passed
through. Sorry about this.

What NetFlow Analyzer can do for you? Monitors network bandwidth and traffic
patterns at an interface-level. Reveals which users, apps, and protocols are
consuming the most bandwidth. Provides multi-vendor support for NetFlow,
J-Flow, sFlow and other flows. Make informed decisions using capacity planning
reports.http://sdm.link/zohodev2dev
