From 8a9cd6d676728792aaee31f30015d284acd154a3 Mon Sep 17 00:00:00 2001 From: Dave Kleikamp Date: Wed, 10 Aug 2005 11:14:39 -0500 Subject: JFS: Fix race in txLock TxAnchor.anon_list is protected by jfsTxnLock (TXN_LOCK), but there was a place in txLock() that was removing an entry from the list without holding the spinlock.
