Hi nfs-ganesha devs who know and love FSAL_MDCACHE,
I'm prototyping an upcall in RGW, and I've quickly hit a fault in
mdc_up_invalidate. It appears clear what's happening: up_ops.invalidate is
mdc_up_invalidate, for which the export argument is expected to be an mdc view
of export--but I've passed my own export handle.
Am I supposed to be recovering an mdc export handle address somewhere, or is
mdc_up_invalidate being unreasonable?
Thanks,
Matt
