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) Signed-off-by: Arjan van de Ven Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- diff --git a/fs/jbd/transaction.c b/fs/jbd/transaction.c index d38e0d575e48..cceaf57e3778 100644 --- a/fs/jbd/transaction.c +++ b/fs/jbd/transaction.c @@ -55,7 +55,7 @@ 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);
