From 772279c5f1dceb58d451dca94b557fd89b1ce890 Mon Sep 17 00:00:00 2001 From: Mingming Cao Date: Wed, 14 May 2008 16:05:41 -0700 Subject: [PATCH] jbd: need to hold j_state_lock to updates to transaction t_state to T_COMMIT Updating the current transaction's t_state is protected by j_state_lock. We need to do the same when updating the t_state to T_COMMIT.
