21 years agoMike's fix for the missing exp_connection oops caused us to not remove
adilger [Fri, 30 Aug 2002 05:16:03 +0000 (05:16 +0000)]
Mike's fix for the missing exp_connection oops caused us to not remove
old exports from the export list.

It also seems wrong, somehow, to be using a lock on the ptlrpc connection

probably make more sense to protect the export list with a lock on the
obd_device.  This is doubly true, because class_new_export() is adding
the export to the obd_device without holding any lock, because there is
no ptlrpc_connection there yet.
