This patch series addresses the causes of flush_to_ldisc accessing
the tty after freeing.
The most common cause stems from the n_tty_close() path spuriously
scheduling buffer work, when the ldisc has already been halted.
This is fixed in 'tty: Don't reschedule buffer work while closing'

The pty driver does not obtain an ldisc reference to the linked

is possible for one ldisc to be halted, and before the second

the first ldisc. This can lead to an

When a new nic is created in namespace ns1, the kernel sends a KOBJ_ADD uevent
to ns1. When the nic is moved to ns2, we only send a KOBJ_MOVE to ns2, and
nothing to ns1.
This patch changes that behavior so that when moving a nic from ns1 to ns2, we
send a KOBJ_REMOVED to ns1 and KOBJ_ADD to ns2.

Here's a patch to handle the "buffer head crosses the end of the disk" case.
It works for me, and in fact it should allow us to
Currently getting the sample period is always thru complex
calculation: get_softlockup_thresh() * ((u64)NSEC_PER_SEC / 5).
But just like the watchdog_thresh, which is not changed often.
So we can store the sample period as a variable, and set it as
__read_mostly type.

This change only affects experimental AoE storage networks.
It modifies the console message about runt packets detected so
that the AoE major and minor addresses of the AoE target that
generated the runt are mentioned.

By default, the aoe driver uses any ethernet interface for AoE,
but the aoe_iflist module parameter provides a convenient way to
limit AoE traffic to a specific list of local network interfaces.
This change allows a list to be specified using the comma
character as a separator. For example,
With this change, the aoe driver treats the value zero as special
for the aoe_deadsecs module parameter. Normally, this value
specifies the number of seconds during which the driver will
continue to attempt retransmits to an unresponsive AoE target.
After aoe_deadsecs has elapsed, the aoe driver

Many AoE targets have four or fewer network ports, but some
existing storage devices have many, and the AoE protocol sets no
limit.
This patch allows the use of more than eight remote MAC addresses
per AoE target, while reducing the amount of memory used by the
aoe driver in cases where there are

This change avoids a race that could result in a NULL pointer
derference following a WARNing from kobject_add_internal, "don't
try to register things with the same name in the same directory."
The problem was found with a test that forgets and discovers an
aoe device in a loop:
while test ! -r
An AoE target can have multiple network ports used for AoE, and
in the aoe driver, those are tracked by the aoetgt struct. These
changes allow the aoe driver to handle network paths, or aoetgts,
that are not working well, compared to the others.
Paths that do not get responses despite the

Looks like this patch is based on linux-next tree, I fixed this. And I
will solve the conflict when we do actually merge in next cycle.
