Josef had changed shrink_delalloc to exit after three shrink
attempts, which wasn't quite enough because new writers could
race in and steal free space.
But it also fixed deadlocks and stalls as we tried to recover
delalloc reservations. The code was tweaked to loop 1024
times, and would reset the counter any time a small amount
of progress was made. This was too drastic, and with a
lot of writers we can end up stuck in shrink_delalloc forever.
The shrink_delalloc loop is fairly complex because the caller is looping
too, and the caller will go ahead and force a transaction commit to make
sure we reclaim space.
This reworks things to exit shrink_delalloc when we've forced some
writeback and the delalloc reservations have gone down. This means
the writeback has not just started but has also finished at
least some of the metadata changes required to reclaim delalloc
space.
If we've got this wrong, we're returning ENOSPC too early, which
is a big improvement over the current behavior of hanging the machine.
Test 224 in xfstests hammers on this nicely, and with 1000 writers
trying to fill a 1GB drive we get our first ENOSPC at 93% full. The
other writers are able to continue until we get 100%.
This is a worst case test for btrfs because the 1000 writers are doing
small IO, and the small FS size means we don't have a lot of room
for metadata chunks.

combinations during emulation
The distance transforming in numa_emulation() used to call
numa_set_distance() for all MAX_NUMNODES * MAX_NUMNODES node
combinations regardless of which are enabled. As numa_set_distance()
ignores all out-of-bound distance settings, this doesn't cause any
problem other than looping unnecessarily many times during boot.
However, as MAX_NUMNODES * MAX_NUMNODES can be pretty high, update the
code such that it iterates through only the enabled combinations.
Yinghai Lu identified the issue and provided an initial patch to
address the issue; however, the patch was incorrect in that it didn't
build emulated distance table when there's no physical distance table
and unnecessarily complex.

This patch splits the pll configs up on pll versions. This allows
easy adding of other known good pll values. Additionally it made it
possible to remove invalid configurations resulting in better
behaviour for such cases. The resulting clocks are no longer stored
resulting in some computing overhead on each mode change.

The clocks can be easily recalculated by the timing and refresh value.
This brings us one step closer to removing VIAs modetable and use
generic ones and being easier extensible.

Before this patch only clocks that perfectly match were used and if
none existed this was not handled properly. This patch changes this
to always use the closest clock supported. This should behave like
before for clocks that have a perfect match but be much saner for
clocks which are slightly off.

This patch removes the direct lookup table for resolution+refresh and
pixclock by calculating this information from the mode table. Removes a
lot of dupllication and error potential by just doing a little more
calculations on each mode change.

On suspend we disable all interrupts in the core code, but this does
not mask the interrupt line in the default implementation as we use a
lazy disable approach. That means we mark the interrupt disabled, but
leave the hardware unmasked. That's an optimization because we avoid
the hardware access for the common case where no interrupt happens
after we marked it disabled. If an interrupt happens, then the
interrupt flow handler masks the line at the hardware level and marks
it pending.
Suspend makes use of this delayed disable as it "disables" all
interrupts when preparing the suspend transition. Right before the
system goes into hardware suspend state it checks whether one of the
interrupts which is marked as a wakeup interrupt came in after
disabling it.
Most interrupt chips have a separate register which selects the
interrupts which can wake up the system from suspend, so we don't have
to mask any on the non wakeup interrupts.
But now we have to deal with brilliant designed hardware which lacks
such a wakeup configuration facility. For such hardware it's necessary
to mask all non wakeup interrupts before going into suspend in order
to avoid the wakeup from random interrupts.
Rather than working around this in the affected interrupt chip
implementations we can solve this elegant in the core code itself.
Add a flag IRQCHIP_MASK_ON_SUSPEND which can be set by the irq chip
implementation to indicate, that the interrupts which are not selected
as wakeup sources must be masked in the suspend path. Mask them in the
loop which checks the wakeup interrupts pending flag.

The latest binutils (2.21.0.20110302/Ubuntu) breaks the build
yet another time, under CONFIG_XEN=y due to a .size directive that
refers to a slightly differently named (hence, to the now very
strict and unforgiving assembler, non-existent) symbol.
[ mingo:
This unnecessary build breakage caused by new binutils
version 2.21 gets escallated back several kernel releases spanning
several years of Linux history, affecting over 130,000 upstream
kernel commits (!), on CONFIG_XEN=y 64-bit kernels (i.e. essentially
affecting all major Linux distro kernel configs).
Git annotate tells us that this slight debug symbol code mismatch
bug has been introduced in 2008 in commit 3d75e1b8:
3d75e1b8 (Jeremy Fitzhardinge 2008-07-08 15:06:49 -0700 1231) ENTRY(xen_do_hypervisor_callback) # do_hypervisor_callback(struct *pt_regs)
The 'bug' is just a slight assymetry in ENTRY()/END()
debug-symbols sequences, with lots of assembly code between the
ENTRY() and the END():
ENTRY(xen_do_hypervisor_callback) # do_hypervisor_callback(struct *pt_regs)
...
END(do_hypervisor_callback)
Human reviewers almost never catch such small mismatches, and binutils
never even warned about it either.
This new binutils version thus breaks the Xen build on all upstream kernels
since v2.6.27, out of the blue.
This makes a straightforward Git bisection of all 64-bit Xen-enabled kernels
impossible on such binutils, for a bisection window of over hundred
thousand historic commits. (!)
This is a major fail on the side of binutils and binutils needs to turn
this show-stopper build failure into a warning ASAP. ]
