From 73195ed7864ae4a1fb0bea2ed9df59d19b4fde90 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sat, 18 Jul 2009 18:14:56 -0400 Subject: [PATCH] xfs: switch to NOFS allocation under i_lock in xfs_da_buf_make i_lock is taken in the reclaim context so all allocations under it must avoid recursions into the filesystem. Reported by the new reclaim context tracing in lockdep.
