From 72772a3b5b158cddcfbbff3ef13b26b03a905158 Mon Sep 17 00:00:00 2001 From: David Chinner Date: Thu, 6 Mar 2008 13:49:43 +1100 Subject: [PATCH] [XFS] fix inode leak in xfs_iget_core() If the radix_tree_preload() fails, we need to destroy the inode we just read in before trying again. This could leak xfs_vnode structures when there is memory pressure. Noticed by Christoph Hellwig.
