Somehow tracepoint_entry_add/remove_probe functions allow a null probe

to be used to remove all probe functions in the entry.

The biggest question is probably if we can use an existing hook of some
sort.
Overriding the apic method is probably not the right way to go, though.

The current code makes the assumption that a cpu_base lock won't
be held if the CPU corresponding to that cpu_base is offline,
which isn't always true.
If a hrtimer is not queued, then it will not be migrated by
migrate_hrtimers() when a CPU is offlined. Therefore, the
hrtimer's cpu_base may

This looks pretty good!
I rather like the (lack of) locking in I/O completion (around the req
count vs. target/queue binding). It is unfortunate that you need to
hold the per-target lock in virtscsi_pick_vq() though; have any idea
how much that lock hurts?

Mm. The question is whether we can reliably determine the ranges a device
should be able to access without having to trust userspace (and, ideally,
without having to worry about whether iommu vendors have done their job). It's
pretty important for PCI passthrough, so we do need to care.

Here's the second version of the patchset.
The intend of the work is get code ready to enable transparent huge page

We have read()/write()/mmap() functionality now.
The cases I'd looked at seemed to mostly involve obsolete hardware or only
allow command submission to SCSI targets, so I wasn't too worried about them -
but, like I said, I've no inherent objection to using CAP_SYS_RAWIO as long as
we modify any cases where userspace really does need that

Well, *unless* you have an iommu
Easiest way to do that would be to replace some existing users of CAP_RAW_IO
with CAP_SYS_ADMIN and then just insert a couple of extra RAW_IO checks. That
would break some existing userspace, but so would introducing a new capability.

Thanks again for your test.

Particularly in oom conditions, it's troublesome that hugetlb memory is
not displayed. All other meminfo that is emitted will not add up to what
is expected, and there is no artifact left in the kernel log to show that
a potentially significant amount of memory is actually allocated as

The named commit (6402c796d3) causes a process to hang indefinitely in
usb_kill_urb(). Reverting it fixes the problem. The bug also prevents
suspend/shutdown/reboot from completing, presumably due to the hanging
process.

No, I suspect the problem is that the debugging code fails to notice
that max_low_pfn isn't set
Currently workqueue->name[] is of flexible length. We want to use the
flexible field for something more useful and there isn't much benefit
in allowing arbitrary name length anyway. Make it fixed len capping
at 24 bytes.

Currently, when exposing attrs of an unbound workqueue via sysfs, the
workqueue_attrs of first_pwq() is used as that should equal the
current state of the workqueue.
The planned NUMA affinity support will make unbound workqueues make
use of multiple pool_workqueues for different NUMA nodes and
Hello,
There are two types of workqueues - per-cpu and unbound. The former
is bound to each CPU and the latter isn't not bound to any by default.
While the recently added attrs support allows unbound workqueues to be
confined to subset of CPUs, it still is quite cumbersome for
applications where
Unbound workqueues are going to be NUMA-affine. Add wq_numa_tbl_len
and wq_numa_possible_cpumask[] in preparation. The former is the
highest NUMA node ID + 1 and the latter is masks of possibles CPUs for
each NUMA node.
This patch only introduces these. Future patches will make use of
them.
Unbound workqueues are now NUMA aware. Let's add some control knobs
and update sysfs interface accordingly.
* Add kernel param workqueue.numa_disable which disables NUMA affinity
globally.
* Replace sysfs file "pool_id" with "pool_ids" which contain
node:pool_id pairs. This change is
Currently, an unbound workqueue has single current, or first, pwq
(pool_workqueue) to which all new work items are queued. This often
isn't optimal on NUMA machines as workers may jump around across node
boundaries and work items get assigned to workers without any regard
to NUMA affinity.
This
Currently, an unbound workqueue has only one "current" pool_workqueue
associated with it. It may have multple pool_workqueues but only the
first pool_workqueue servies new work items. For NUMA affinity, we
want to change this so that there are multiple current pool_workqueues
serving different
