From f41d7fb9da05b604f8a69fb6cac2a0563c8ede4e Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sat, 18 Jul 2009 18:14:55 -0400 Subject: xfs: switch to NOFS allocation under i_lock in xfs_da_state_alloc xfs_da_state_alloc 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.
