From db857da3369cd4eb6a28be1cce89d33162caa4a0 Mon Sep 17 00:00:00 2001 From: Mingming Cao Date: Mon, 28 Jan 2008 23:58:27 -0500 Subject: jbd2: Use round-jiffies() function for the "5 second" ext4/jbd2 wakeup While "every 5 seconds" doesn't sound as a problem, there can be many of these (and these timers do add up over all the kernel). The "5 second" wakeup isn't really timing sensitive; in addition even with rounding it'll still happen every 5 seconds (with the exception of the very first time, which is likely to be rounded up to somewhere closer to 6 seconds) (Ported from similar JBD patch made by Arjan van de Ven to fs/jbd/transaction.c) Cc: Arjan van de Ven Cc: Andrew Morton Signed-off-by: Mingming Cao Signed-off-by: "Theodore Ts'o" --- fs/jbd2/transaction.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'fs/jbd2') diff --git a/fs/jbd2/transaction.c b/fs/jbd2/transaction.c index 70b3199e69d..0c8adaba0c0 100644 --- a/fs/jbd2/transaction.c +++ b/fs/jbd2/transaction.c @@ -54,7 +54,7 @@ jbd2_get_transaction(journal_t *journal, transaction_t *transaction) spin_lock_init(&transaction->t_handle_lock); /* Set up the commit timer for the new transaction. */ - journal->j_commit_timer.expires = transaction->t_expires; + journal->j_commit_timer.expires = round_jiffies(transaction->t_expires); add_timer(&journal->j_commit_timer); J_ASSERT(journal->j_running_transaction == NULL); -- cgit v1.2.3
