accounting.
The default 5/10 dirty ratios were picked (a) with the old dirty logic

particular, that (a) means that having fixed some of the dirty
accounting, maybe the real bug is now that it was always too aggressive,
just hidden by an accounting issue.

block: WARN in __blk_put_request() for potential bio leak
Put a WARN_ON in __blk_put_request if it is about to
leak bio(s). This is a serious bug that can happen in error
handling code paths.
For this to work I have fixed a couple of places in block/ where
request->bio != NULL ownership was not honored. And a small cleanup
at sg_io() while at it.
triggers a [ INFO: possible circular locking dependency detected ]
I think this warning is a false positive.
Open/close on a loop device acquires bd_mutex of the device before
acquiring lo_ctl_mutex of the same device. For ioctl(LOOP_CLR_FD) after
acquiring lo_ctl_mutex, fput on the backing_file might acquire the bd_mutex of
a device, if backing file is a device and this is the last reference to the
file being dropped . But it is guaranteed that it is impossible to have a
circular list of backing devices.(say loop2->loop1->loop0->loop2 is not
possible), which guarantees that this can never deadlock.
So this warning should be suppressed. It is very difficult to annotate lockdep
not to warn here in the correct way. A simple way to silence lockdep could be
to mark the lo_ctl_mutex in ioctl to be a sub class, but this might mask some
other real bugs.
@@ -1164,7 +1164,7 @@ static int lo_ioctl(struct block_device *bdev, fmode_t mode,
struct loop_device *lo = bdev->bd_disk->private_data;
int err;
Or actually marking the bd_mutex after lo_ctl_mutex as a sub class could be
a better solution.
Luckily it is easy to avoid calling fput on backing file with lo_ctl_mutex
held, so no lockdep annotation is required.
If you do not like the special handling of the lo_ctl_mutex just for the
LOOP_CLR_FD ioctl in lo_ioctl(), the mutex handling could be moved inside
each of the individual ioctl handlers and I could send you another patch.

e1000e (and e1000, igb, ixgbe, ixgb) all do a series of operations each
time a multicast address is added. The flow goes something like
1) stack adds one multicast address
2) stack passes whole current list of unicast and multicast addresses to
driver
3) driver clears entire list in hardware
4) driver programs each multicast address using iomem in a loop
This was causing multicast packets to be lost during the reprogramming
process.
reference with test program:
http://kerneltrap.org/mailarchive/linux-netdev/2009/3/14/5160514/thread
Thanks to Dave Boutcher for his report and test program.
This driver fix prepares an array all at once in memory and programs it in
one shot to the hardware, not requiring an "erase" cycle. It would still
be possible for packets to be dropped while the receiver is off during
reprogramming.

bonding: select current active slave when enslaving device for mode tlb and alb
I've hit an issue on my system when I've been using RealTek RTL8139D cards in

active slave (bond->curr_active_slave) is not set and the link is therefore
not functional.

The thing that gets it right is when I unplug the cable and then I put it back
into the NIC. Then the current active slave is set to eth1 and link is working
just fine. Here is dmesg log with bonding DEBUG messages turned on:

The current active slave is set by calling bond_select_active_slave() function
from bond_miimon_commit() function when the slave (eth1) link goes to state up.
I also tested this on other machine with Broadcom NetXtreme II BCM5708
1000Base-T NIC and there all works fine. The thing is that this adapter is down
and goes up after few seconds after it is enslaved.
This patch calls bond_select_active_slave() in bond_enslave() function for modes
alb and tlb and makes sure that the current active slave is set up properly even
when the slave state is already up. Tested on both systems, works fine.

test that.
