I know Linus is not taking cleanups at this point, but perhaps
you can delete it in your tree. Seems like someone (Oliver?)
fixed all the garbage in old printer.c, so the comment is not
needed anymore.

I reviewed changes, and usblp.c looks correct. I'm doing backport
to 2.4 for Fedora right now.

Just for cdc-acm, it pushes RX URB processing into a tasklet;
and has minor cleanups.

I cc'd Vojtech since he's this driver's maintainer.  If this
checks out, usb-serial will need similar changes.


p.s. the issue is a WARN_ON that tells us:

The pid_alive() check within the loop is incorrect.  If we are within
the tasklist lock and the thread group leader is valid then the thread
chain will be fully intact.

Instead, the check should be _outside_ the loop, since if the group
leader no longer exists, the whole list is gone and we must not try
to access it.

Move the check around, and add comment.

Bug-hunting and fix by Srivatsa Vaddagiri

When doing sync wakeups we must not skip the notification of other cpus
if the task is not on this runqueue.

We need to initialize st->state in tcp_seq_start().  Otherwise
tcp_seq_stop() is run with previous st->state, and it calls the unneeded
unlock etc, causing a kernel crash.

I've got a lot more changes than what's included here.  I've put this
down to the bear minimum to get things working sanely.

Mainly, I just want to get all the people hit by this a chance to use
2.6.0 without having to get our tree. Changes itemized:

 - Fix deadlock possibility in csr.c:read_maps()
 - Fix kmalloc to use ATOMIC in highlevel.c.
 - s/in_interrupt/irqs_disabled/ in ieee1394_transactions.c to fix
   warnings when transactions occured.
 - Introduce a release callback for the host driver and use it correctly.
 - Reorganize the nodemgr probe so we do an initial scan to discover
   devices, check IRM/CycleMaster, then do a final full probe when things
   are kosher. Fixes a problem where device registration and hotplug
   would cause some serious problems when a bus reset was forced in the
   middle of the probe.

There are /proc handles there setup by proc_tty_register_driver, but there is
no module ownership association, so anything that reads after module unload
will blow.

The trivial fix is to propagate the owner of tty_driver to proc entry.

This fixes a small, but important bug in smsc-ircc2.c.

Without this the driver tries release the same region twice.

      Tracked down by Rohit Seth.

Do not special case ENOMEM as an error code, we should free up
the packet for all errors.

Most of the breakage came from cset 1.838.10.3

The br_netfilter_{init,fini}() calls need to be guarded by
BRIDGE_NETFILTER, from Michal Janusz Miroslaw.

When bringing an interface down do not forget to clear the
IF_RS_SENT and IF_RA_RCVD flags.

This fixes an oops that can occur if JFS is used as the root filesystem.

Writes to a device node may cause a ->write_inode to be called during a
read-only mount.  JFS needs to check for NULL log in jfs_flush_journal.

Also, make sure NET_RX_DROP is returned if we did not accept the
packet.

In implementations that use no socket locking, such as RAW sockets,
once we queue the SKB to the socket another cpu can remove the SKB
from the socket queue and free up the SKB making the skb->len access
touch freed memory.

Also add some ServerWorks-specific tweaks.

All the users of this function in the SCSI tree call it with the host
lock held.  With the new list traversal code, it was trying to take
the lock again to traverse the list.

Fix it to use the unlocked version of list traversal and modify the
header comments to make it clear that the lock is expected to be held
on calling it.
