The patch titled user of the jiffies rounding code: JBD has been added to the -mm tree. Its filename is user-of-the-jiffies-rounding-code-jbd.patch See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find out what to do about this ------------------------------------------------------ Subject: user of the jiffies rounding code: JBD From: Arjan van de Ven <arjan@xxxxxxxxxxxxxxx> This patch introduces a user: of the round_jiffies() function; the "5 second" ext3/jbd 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) Signed-off-by: Arjan van de Ven <arjan@xxxxxxxxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxx> --- fs/jbd/transaction.c | 2 +- 1 files changed, 1 insertion(+), 1 deletion(-) diff -puN fs/jbd/transaction.c~user-of-the-jiffies-rounding-code-jbd fs/jbd/transaction.c --- a/fs/jbd/transaction.c~user-of-the-jiffies-rounding-code-jbd +++ a/fs/jbd/transaction.c @@ -53,7 +53,7 @@ get_transaction(journal_t *journal, tran 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); _ Patches currently in -mm which might be from arjan@xxxxxxxxxxxxxxx are origin.patch sleazy-fpu-feature-i386-support.patch remove-the-old-bd_mutex-lockdep-annotation.patch new-bd_mutex-lockdep-annotation.patch round_jiffies-infrastructure.patch round_jiffies-infrastructure-fix.patch user-of-the-jiffies-rounding-patch-ata-subsystem.patch user-of-the-jiffies-rounding-code-jbd.patch user-of-the-jiffies-rounding-code-networking.patch user-of-the-jiffies-rounding-patch-slab.patch - To unsubscribe from this list: send the line "unsubscribe mm-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
