From 3f52c2f0a07c23771909cc53f2e9451a7f1bf253 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sat, 18 Jul 2009 18:14:57 -0400 Subject: xfs: switch to NOFS allocation under i_lock in xfs_dir_cilookup_result xfs_dir_cilookup_result is always called with i_lock held, but i_lock is taken in reclaim context so all allocations under it must avoid recursions into the filesystem. Reported by the new reclaim context tracing in lockdep.
