Switch to the new driver allocation interface, as this is one of the
special call-sites. Here, we need TTY_DRIVER_DYNAMIC_ALLOC to not
allocate tty_driver->ports, cdevs and potentially other structures
because we reserve too many lines in pty. Instead, it provides the
tty_port<->tty_struct link in
We need the /dev/ node not to be available before we call
tty_register_device. Otherwise we might race with open and
tty_struct->port might not be available at that time.
This is not an issue now, but would be a problem after "TTY: use
tty_port_register_device" is applied.

This allows drivers like ttyprintk to avoid hacks to create an
unnumbered node in /dev. It used to set TTY_DRIVER_DYNAMIC_DEV in
flags and call device_create on its own. That is incorrect, because
TTY_DRIVER_DYNAMIC_DEV may be set only if tty_register_device is
called explicitly.

So now, that we have flags and know everything needed, keep a promise
and move all the tables and ports allocation from tty_register_driver
to tty_alloc_driver.
Not only that it makes sense, but we need this for
tty_port_link_device which needs tty_driver->ports but is to be called
before tty_regi

Hi
The problem with the patch is that it changes interface to the userspace
tool. The userspace tool veritysetup already exists in recent cryptsetup
package, so we can't change the interface - you should change the patch so
that the starting data block is the last argument and the argument is
nux/kernel/people/andrea/autonuma/autonuma-vs-sched-numa-rewrite-20120808.pdf
For the people who have not yet read that PDF:

current version does not seem to offer a significant
performance improvement over not having it, and in one of

I realize that we have the same issue with the virtio rings.
Are there any way we can assign the device address of the virtio

Hi Seth --
Good discussion. Even though we disagree, I appreciate
your enthusiasm and your good work on the kernel!

I recently investigated the I/O performance of some software and
noticed that "iotop" and "pidstat -d" reported way more write activity
than the application could ever have written.
Further investigation revealed that the application was using

Nobody does set_orig_insn(verify => false), and I think nobody will.
Remove this argument. IIUC set_orig_insn(verify => false) was needed
to single-step without xol area.

Add the new MMF_HAS_UPROBES flag. It is set by install_breakpoint()
and it is copied by dup_mmap(), uprobe_pre_sstep_notifier() checks
it to avoid the slow path if the task was never probed. Perhaps it
makes sense to check it in valid_vma(is_register => false) as well.
This needs the new dup_mmap(
Once install_breakpoint() fails uprobe_mmap() "ignores" all other
uprobes and returns the error.
It was never really needed to to stop after the first error, and
in fact it was always wrong at least in -ENOTSUPP case.
Change uprobe_mmap() to ignore the errors and always return 0.
This is not what
-EEXIST from install_breakpoint() no longer makes sense, all
callers should simply treat it as "success". Change the code
to return zero and simplify register_for_each_vma().

Now that we have uprobe_dup_mmap() we can fold uprobe_reset_state()
into the new hook and remove it. mmput()->uprobe_clear_state() can't
be called before dup_mmap().

uprobes_state->count is only needed to avoid the slow path in
uprobe_pre_sstep_notifier(). It is also checked in uprobe_munmap()
but ironically its only goal to decrement this counter. However,
it is very broken. Just some examples:

Hello.
Srikar, please review.
This is the first part. The next series will teach uprobes to
clear MMF_HAS_UPROBES, but perhaps we should simply remove
uprobe_munmap() instead. A wrong MMF_HAS_UPROBES doesn't hurt
unless the task hits the non-uprobe "int3", not sure it really
