In the meantime, disable merging for noop by setting REQ_NOMERGE in

Eventually, we should add a noop_list and do the dispatching like in the

always done it).

this happens when the desired frequency exceeds 61 Hz.

To avoid this multiplication, we can precompute and store the hardware
timer frequency, instead of the period, in the device structure, which
leaves us with a simple division when computing the number of timer ticks.

As a side effect, this also removes a theoretical bug where the timer
interpolator's frequency would be computed as a 32-bit value even if the

This patch is a rewrite of the one submitted on October 1st, using modules
(http://marc.theaimsgroup.com/?l=linux-kernel&m=112819093522998&w=2).

This rewrite adds a tristate CONFIG_RCU_TORTURE_TEST, which enables an
intense torture test of the RCU infratructure.  This is needed due to the
continued changes to the RCU infrastructure to accommodate dynamic ticks,
CPU hotplug, realtime, and so on.  Most of the code is in a separate file
that is compiled only if the CONFIG variable is set.  Documentation on how
to run the test and interpret the output is also included.

This code has been tested on i386 and ppc64, and an earlier version of the
code has received extensive testing on a number of architectures as part of
the PREEMPT_RT patchset.

This patch fixes a long-standing vgacon bug: characters with the bright bit
set were left on the screen and not blacked out.  All I did was that I

added the call missing from the linux kernel, but included in all other
ones.  It works for me.

You can test this by writing something with the bright set to the
console, for example:
  echo -e "\e[1;31mhello there\e[0m"
and then wait for the console to blank itself (by default, after 10 mins
of inactivity), maybe making it faster using
  setterm -blank 1
so you only have to wait 1 minute.

16 years ago[PATCH] fix nr_unused accounting, and avoid recursing in iput with I_WILL_FREE set
Andrea Arcangeli [Sun, 30 Oct 2005 23:03:05 +0000 (15:03 -0800)]
[PATCH] fix nr_unused accounting, and avoid recursing in iput with I_WILL_FREE set

  list_move(&inode->i_list, &inode_in_use);
  } else {
  list_move(&inode->i_list, &inode_unused);
+ inodes_stat.nr_unused++;
  }
  }
  wake_up_inode(inode);

Are you sure the above diff is correct? It was added somewhere between
2.6.5 and 2.6.8. I think it's wrong.

The only way I can imagine the i_count to be zero in the above path, is
that I_WILL_FREE is set.  And if I_WILL_FREE is set, then we must not
increase nr_unused.  So I believe the above change is buggy and it will
definitely overstate the number of unused inodes and it should be backed
out.

Note that __writeback_single_inode before calling __sync_single_inode, can
drop the spinlock and we can have both the dirty and locked bitflags clear
here:

spin_unlock(&inode_lock);
__wait_on_inode(inode);
iput(inode);
XXXXXXX
spin_lock(&inode_lock);
}
use inode again here

a construct like the above makes zero sense from a reference counting
standpoint.

Either we don't ever use the inode again after the iput, or the
inode_lock should be taken _before_ executing the iput (i.e. a __iput
would be required). Taking the inode_lock after iput means the iget was
useless if we keep using the inode after the iput.

So the only chance the 2.6 was safe to call __writeback_single_inode
with the i_count == 0, is that I_WILL_FREE is set (I_WILL_FREE will
prevent the VM to free the inode in XXXXX).

Potentially calling the above iput with I_WILL_FREE was also wrong
because it would recurse in iput_final (the second mainline bug).

The below (untested) patch fixes the nr_unused accounting, avoids recursing
in iput when I_WILL_FREE is set and makes sure (with the BUG_ON) that we
don't corrupt memory and that all holders that don't set I_WILL_FREE, keeps
a reference on the inode!
