From 76d095388b040229ea1aad7dea45be0cfa20f589 Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Tue, 12 Jun 2012 14:20:26 +1000 Subject: [PATCH] xfs: fix allocbt cursor leak in xfs_alloc_ag_vextent_near When we fail to find an matching extent near the requested extent specification during a left-right distance search in xfs_alloc_ag_vextent_near, we fail to free the original cursor that we used to look up the XFS_BTNUM_CNT tree and hence leak it.
