mm/kmemleak-test.c is used to provide an example of how kmemleak
tool works.
Memory is leaked at module unload-time, so building the test
in kernel (Y) makes the leaks impossible and the test useless.
Qualify DEBUG_KMEMLEAK_TEST config symbol with "depends on m",
to restrict module-only building.

Commit f23eb2b2b285 ('tty: stop using "delayed_work" in the tty layer')
ended up causing hung machines on UP with no preemption, because the
work routine to flip the buffer data to the ldisc would endlessly re-arm
itself if the destination buffer had filled up.
With the delayed work, that only caused a timer-driving polling of the
tty state every timer tick, but without the delay we just ended up with
basically a busy loop instead.
Stop the insane polling, and instead make the code that opens up the
receive room re-schedule the buffer flip work. That's what we should
have been doing anyway.
This same "poll for tty room" issue is almost certainly also the cause
of excessive kworker activity when idle reported by Dave Jones, who also
reported "flush_to_ldisc executing 2500 times a second" back in Nov 2010:
http://lkml.org/lkml/2010/11/30/592
which is that silly flushing done every timer tick. Wasting both power
and CPU for no good reason.

In ext4_register_li_request, we malloc a ext4_li_request and
inserts it into ext4_li_info->li_request_list. In case of any
error later, we free it in the end. But if we have some error
in ext4_run_lazyinit_thread, the whole li_request_list will be
dropped and freed in it. So we will double free this ext4_li_request.
This patch just sets elr to NULL after it is inserted to the list
so that the latter kfree won't double free it.

When writing a contiguous set of blocks, two indirect blocks could be

[ Also fixed a another bug which could further underestimate the

division instead of DIV_ROUND_UP() -- tytso]

It is not necessary to update [cm]time of quota file on each quota
file write and it wastes journal space and IO throughput with inode
writes. So just remove the updating from ext4_quota_write() and only
update times when quotas are being turned off. Userspace cannot get
anything reliable from quota files while they are used by the kernel
anyway.

We were allocating the size of the NVS file struct and not checking
whether the length of the buffer passed was correct before copying it
into the allocated memory. This is a security hole because buffer
overflows can occur if the userspace passes a bigger file than what is
expected.
With this patch, we check if the size of the data passed from
userspace matches the size required.
This bug was introduced in 2.6.36.

Patch removes the bogus flag introduced by upstream commit
eefdbec1ea8b7093d2c09d1825f68438701723cf. Old code had buffer length check
that new code tried to handle with URB_SHORT_NOT_OK flag. With USB debugging
enabled bogus flag caused usb_submit_urb fail.
Remove URB_SHORT_NOT_OK flag and add buffer length check to urb completion
handler.

The description for buf_size was misleading and
just said you couldn't TX larger aggregates, but
of course you can't TX aggregates in a way that
would exceed the window either, which is possible
even if the aggregates are shorter than that.

There are valid situations in which this error is not
a warning. Mainly when QEMU maps a guest memory and uses
the VM_IO flag to set the MFNs. For right now make the
WARN be WARN_ONCE. In the future we will:
1). Remove the VM_IO code handling..
2). .. which will also remove this debug facility.
