This case is an update to PSARC 2007/456 Vnode Specific Data and adds a new field to the vnode structure (in sys/vnode.h): v_vsd_lock. The case seeks Minor binding which matches the binding of the original case. The timer expires on June 12, 2009. Template Version: @(#)sac_nextcase 1.68 02/23/09 SMI This information is Copyright 2009 Sun Microsystems 1. Introduction 1.1. Project/Component Working Name: VSD locking update 1.2. Name of Document Author/Supplier: Author: Bob Mastors 1.3 Date of This Document: 05 June, 2009 4. Technical Description PSARC 2007/456 Vnode Specific Data was created to easily associate project specific data with a vnode. The current implementation requires consumers of vsd_get() and vsd_set() to hold the vnode v_lock mutex across the calls. However, vsd_set() may go to sleep on kmem_alloc(). This could cause the system to deadlock if the vnode had dirty pages that needed to be written. This problem is described by: 6839233 VSD usage of v_lock could cause deadlock The solution adds a new mutex to vnode_t: kmutex_t v_vsd_lock; /* protects v_vsd field */ Consumers of vsd_get() and vsd_set() would hold v_vsd_lock across the calls instead of v_lock. There are no lock ordering issues since the locks are independent and there is no reason to hold both simultaneously. Currently, the only ON consumer of vsd_get() and vsd_set() is NFS.

I have copies of the mail thread in case anyone wishes to review them.
