From b2ce39740066604288876c752d8170b3b17a21aa Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Mon, 11 Jul 2011 09:51:44 -0500 Subject: [PATCH] Revert "xfs: fix filesystsem freeze race in xfs_trans_alloc" This reverts commit 7a249cf83da1813cfa71cfe1e265b40045eceb47. That commit created a situation that could lead to a filesystem hang. As Dave Chinner pointed out, xfs_trans_alloc() could hold a reference to m_active_trans (i.e., keep it non-zero) and then wait for SB_FREEZE_TRANS to complete. Meanwhile a filesystem freeze request could set SB_FREEZE_TRANS and then wait for m_active_trans to drop to zero. Nobody benefits from this sequence of events...
