Hi,
Thanks everybody for your valuable information.
I am not aware of all these dma related APIs but where to handle these dma
stuff?
Is it in UBI/UBIFS(at the time of vmalloc allocations)? Or in controller driver?
And also is there a way to know the memory allocated using vmalloc is

Currently, each container shared one copy of coredump setting
with the host system, if host system changed the setting, each
running containers will be affected.
Same story happened when container changed core_pattern, both
host and other container will be affected.
For container
Current call_usermodehelper_work() can not set namespaces for
the executed program.
This patch add above function for call_usermodehelper_work().
The init_intermediate is introduced for init works which should
be done before fork(). So that we get a method to set namespaces
for children. The clean
Currently when we set core_pattern to a pipe, the pipe program is
forked by kthread running with root's permission, and write dumpfile
into host's filesystem.
Same thing happened for container, the dumper and dumpfile are also
in host(not in container).
It have following program:
1: Not consistent
Current code returns EXDEV when a directory would need to be copied up to
move. We could copy up the directory tree in this case, but there's
another solution: point to old lower directory from moved upper directory.
This is achieved with a "trusted.overlay.redirect" xattr storing the path

This allows overlayfs to move directory trees (residing on lower layer)
without having to recursively copy up the whole tree first.

When this flag is set for CAPTURE queues by the driver on calling
vb2_queue_init(), it forces the buffers on the queue to be

As there are no users left, we can remove cpu_relax_lowlatency.

stop_machine seemed to be the only important place for yielding during
cpu_relax. This was fixed by using cpu_relax_yield. Therefore, we can
now redefine cpu_relax to be a barrier instead on s390, making s390
identical to all other architectures.

Some time ago commit 57f2ffe14fd125c2 ("s390: remove diag 44 calls
from cpu_relax()") did stop cpu_relax on s390 yielding to the
hypervisor.
As it turns out this made stop_machine run really slow on virtualized
overcommited systems. For example the kprobes test during bootup took
several seconds
With the s390 special case of a yielding cpu_relax implementation gone,
we can now remove all users of cpu_relax_lowlatency and replace them
with cpu_relax.

For spinning loops people do often use barrier() or cpu_relax().
For most architectures cpu_relax and barrier are the same, but on
some architectures cpu_relax can add some latency.
For example on power,sparc64 and arc, cpu_relax can shift the CPU
towards other hardware threads in an SMT environmen
Peter,
here is v2 with some improved patch descriptions and some fixes. The
previous version has survived one day of linux-next and I only changed
small parts.
So unless there is some other issue, feel free to pull (or to apply
the patches) to tip/locking.

This patch introduces bugs. It's my policy to not explain the Markus's
bugs because otherwise he will just resend the patchset and I have asked
him many times to stop.
I will happily review bug fix patches but I really think he should stop
sending these cleanup patches.

Since you're redoing this anyway, please split this one into two
patches. We really frown on mixing

Brace expansion might not work properly if _buildshell RPM macro
points to a shell other than bash. Particularly, with _bulidshell
defined to /bin/dash it leads to broken build and source symlinks.

There is a single phy control in the system for both 1.1 and 2.0 PHYs.
so this can be a singular device (id -1)
Hi Hannes,
Please give us little more info on the third comment. It ll help us to
understand better and
incorporate required changes.
Comment is "Why don't you need to check for the size of the bitmap here?"
