I tried to convert both restart and reset to use msleep's with work
queue, but if we do that, host_set lock should be released after
initiating restart or reset, leading to race condition among

NeilBrown [Fri, 18 Nov 2005 09:11:01 +0000 (01:11 -0800)] 
[PATCH] md: fix is_mddev_idle calculation now that disk/sector accounting happens when request completes

md needs to monitor the rate of requests to its devices when doing
resync/recovery so that it can back-off when there is non-resync IO.  It
does this by comparing resync IO, which it counts, with total IO which is
taken from disk_stats.

disk_stats were recently changed to account sectors when a request
completes instead of when it is queued.  This upsets md's calculations.

We could do the sync_io accounting at the end of requests too, but that has
problems.  If an underlying device is an md array, the accounting will
still be done when the request is submitted.  This could be changed for
some raid levels, but it cannot be changed for raid0 or linear without
substantial code changes.

So instead, we increase the error that is_mddev_idle allows, up to the
maximum amount of resync IO that can be in flight at any time.  The
calculation is current fragile as each personality as different limits for
in-flight resync.  This should be fixed up.

For now, this simple patch fixes the problem.

Increasing the error margin decreases the sensitivity to non-resync IO.  To
partially compensate for this, the time to wait when non-resync IO is
detected is increased so that less steady IO is required to keep the resync
at bay.

Ryan Bradetich [Thu, 17 Nov 2005 21:38:28 +0000 (16:38 -0500)] 
[PARISC] Define port->timeout to fix a long msleep in mux.c

This commit is in response to a bug reported by Vesa on the irc channel
a couple of weeks ago.

The bug was that the console would apparently hang (not return) while
using the mux console.

The root cause of this bug is that bash (with readline support) makes a
call to the tcsetattr() glibc function with the argument TCSADRAIN.  This
causes the serial core in the kernel use the uart_wait_until_sent() to be
called. This function verifies the mux transmit queue is empty or calls the
msleep_interruptable() with a calculated timeout value that is dependant
upon the port->timeout variable.

The real problem here is that the port->timeout was not defined so it
was defaulted to 0 and the timeout calculation performs the following
calculation:

char_time = (port->timeout - HZ/50) / port->fifosize;

where char_time is an unsigned long. Since the serial Mux does not use
interrupts, the msleep_interruptable() function waits until the timeout
has been reached ... and when the port->timeout < HZ/50 this timeout will
be a long time. (I have validated that the console will eventually
return ... but it takes quite a while for this to happen).

This patch simply sets the port->timeout on the Mux to HZ/50 to avoid
this long timeout period.

[PARISC] Fix our spinlock implementation

We actually have two separate bad bugs

1. The read_lock implementation spins with disabled interrupts.  This is
completely wrong
2. Our spin_lock_irqsave should check to see if interrupts were enabled
before the call and re-enable interrupts around the inner spin loop.

The problem is that if we spin with interrupts off, we can't receive
IPIs. This has resulted in a bug where SMP machines suddenly spit
smp_call_function timeout messages and hang.

The scenario I've caught is

CPU0 does a flush_tlb_all holding the vmlist_lock for write.
CPU1 tries a cat of /proc/meminfo which tries to acquire vmlist_lock for
     read
CPU1 is now spinning with interrupts disabled
CPU0 tries to execute a smp_call_function to flush the local tlb caches

This is now a deadlock because CPU1 is spinning with interrupts disabled
and can never receive the IPI
