From 10746e47e722b5688fcd6eba9fbf9b2e64a248a7 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sat, 18 Jul 2009 18:14:59 -0400 Subject: xfs: switch to NOFS allocation under i_lock in xfs_attr_rmtval_set xfs_attr_rmtval_set is always called with i_lock held, and 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.
