This fixes the panic which happens when mdcreate_vnode() calls vn_close() and mddestroy() calls it again further down the error handling path. Commit 14/14 of sched_lock decomposition. 2007-06-05T00:00:57Z Jeff Roberson jeff@FreeBSD.org 2007-06-05T00:00:57Z urn:sha1:982d11f836278f1e95ae1ae398aa4d1d07a19006 - Use thread_lock() rather than sched_lock for per-thread scheduling sychronization. - Use the per-process spinlock rather than the sched_lock for per-process scheduling synchronization.
