From 0123c93998511978556b03d2bb023af92aa24d55 Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Fri, 1 Aug 2008 20:57:54 -0400 Subject: [PATCH] ext4: Fix ext4_ext_journal_restart() The ext4_ext_journal_restart() is a convenience function which checks to see if the requested number of credits is present, and if so it closes the current transaction and attaches the current handle to the new transaction. Unfortunately, it wasn't proprely checking the return value from ext4_journal_extend(), so it was starting a new transaction when one was not necessary, and returning an error when all that was necessary was to restart the handle with a new transaction.
