From 034772b068be62a79470d6c1b81b01fbe27793ac Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Tue, 3 Jun 2008 22:31:11 -0400 Subject: jbd2: Fix barrier fallback code to re-lock the buffer head If the device doesn't support write barriers, the write is retried without ordered mode. But the buffer head needs to be re-locked or submit_bh will fail with on BUG(!buffer_locked(bh)).
