2.6.27-stable review patch. If anyone has any objections, please let us know. ------------------ From: Jan Kara <jack@xxxxxxx> (cherry picked from commit 9eddacf9e9c03578ef2c07c9534423e823d677f8) This undoes commit 14ce0cb411c88681ab8f3a4c9caa7f42e97a3184. Since jbd2_journal_start_commit() is now fixed to return 1 when we started a transaction commit, there's some transaction waiting to be committed or there's a transaction already committing, we don't need to call ext4_force_commit() in ext4_sync_fs(). Furthermore ext4_force_commit() can unnecessarily create sync transaction which is expensive so it's worthwhile to remove it when we can. http://bugzilla.kernel.org/show_bug.cgi?id=12224 Signed-off-by: Jan Kara <jack@xxxxxxx> Signed-off-by: "Theodore Ts'o" <tytso@xxxxxxx> Cc: Eric Sandeen <sandeen@xxxxxxxxxx> Cc: linux-ext4@xxxxxxxxxxxxxxx Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxx> --- fs/ext4/super.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) --- a/fs/ext4/super.c +++ b/fs/ext4/super.c @@ -2950,14 +2950,14 @@ static void ext4_write_super(struct supe static int ext4_sync_fs(struct super_block *sb, int wait) { - int ret = 0; + tid_t target; sb->s_dirt = 0; - if (wait) - ret = ext4_force_commit(sb); - else - jbd2_journal_start_commit(EXT4_SB(sb)->s_journal, NULL); - return ret; + if (jbd2_journal_start_commit(EXT4_SB(sb)->s_journal, &target)) { + if (wait) + jbd2_log_wait_commit(EXT4_SB(sb)->s_journal, target); + } + return 0; } /* -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
