From c61b3e4839007668360ed8b87d7da96d2e59fc6c Mon Sep 17 00:00:00 2001 From: Dave Kleikamp Date: Fri, 13 Nov 2020 14:58:46 -0600 Subject: jfs: Fix array index bounds check in dbAdjTree Bounds checking tools can flag a bug in dbAdjTree() for an array index out of bounds in dmt_stree. Since dmt_stree can refer to the stree in both structures dmaptree and dmapctl, use the larger array to eliminate the false positive.
