After a lot of reading the code and thinking about how it behaves I have
managed to figure out what the current ptrace locking rules are. The
current code is in much better that it appears at first glance. The
troublesome code paths are actually the code paths that violate the current
rules.
ptrace uses simple exclusive access as it's locking. You can only touch
task->ptrace if the task is stopped and you are the ptracer, or if the task
is running and are the task itself.
Very simple, very easy to maintain. It just needs to be documented so
people know not to touch ptrace from elsewhere.
Currently we do have a few pieces of code that are in violation of this
rule. Particularly the core dump code, and ptrace_attach. But so far the
code looks fixable.

The "count" and "pt" variables are declared and modified by do_poll(), as
well as accessed and written indirectly in the do_pollfd() subroutine.
This patch pulls all handling of these variables into the do_poll()
function, thereby eliminating the odd use of indirection in do_pollfd().
This is done by pulling the "struct pollfd" traversal loop from do_pollfd()
into its only caller do_poll(). As an added bonus, the patch saves a few
clock cycles, and also adds comments to make the code easier to follow.

Pass the POSIX lock owner ID to the flush operation.
This is useful for filesystems which don't want to store any locking state
in inode->i_flock but want to handle locking/unlocking POSIX locks
internally. FUSE is one such filesystem but I think it possible that some
network filesystems would need this also.
Also add a flag to indicate that a POSIX locking request was generated by
close(), so filesystems using the above feature won't send an extra locking
request in this case.

posix_lock_file() always allocates new locks in advance, even if it's easy to
determine that no allocations will be needed.

posix_lock_file() was too cautious, failing operations on OOM, even if they
didn't actually require an allocation.
This has the disadvantage, that a failing unlock on process exit could lead to
a memory leak. There are two possibilites for this:
- filesystem implements .lock() and calls back to posix_lock_file(). On
cleanup of files_struct locks_remove_posix() is called which should remove all
locks belonging to files_struct. However if filesystem calls
posix_lock_file() which fails, then those locks will never be freed.
- if a file is closed while a lock is blocked, then after acquiring
fcntl_setlk() will undo the lock. But this unlock itself might fail on OOM,
again possibly leaking the lock.
The solution is to move the checking of the allocations until after it is sure
that they will be needed. This will solve the above problem since unlock will
always succeed unless it splits an existing region.

On zSeries machines there exists an interface which allows the operating
system to retrieve LPAR hypervisor accounting data. For example, it is
possible to get usage data for physical and virtual cpus. In order to
provide this information to user space programs, I implemented a new
virtual Linux file system named 's390_hypfs' using the Linux 2.6 libfs
framework. The name 's390_hypfs' stands for 'S390 Hypervisor Filesystem'.
All the accounting information is put into different virtual files which
can be accessed from user space. All data is represented as ASCII strings.
When the file system is mounted the accounting information is retrieved and
a file system tree is created with the attribute files containing the cpu
information. The content of the files remains unchanged until a new update
is made. An update can be triggered from user space through writing
'something' into a special purpose update file.
We create the following directory structure:
<mount-point>/
update
cpus/
<cpu-id>
type
mgmtime
<cpu-id>
...
hyp/
type
systems/
<lpar-name>
cpus/
<cpu-id>
type
mgmtime
cputime
onlinetime
<cpu-id>
...
<lpar-name>
cpus/
...
- update: File to trigger update
- cpus/: Directory for all physical cpus
- cpus/<cpu-id>/: Directory for one physical cpu.
- cpus/<cpu-id>/type: Type name of physical zSeries cpu.
- cpus/<cpu-id>/mgmtime: Physical-LPAR-management time in microseconds.
- hyp/: Directory for hypervisor information
- hyp/type: Typ of hypervisor (currently only 'LPAR Hypervisor')
- systems/: Directory for all LPARs
- systems/<lpar-name>/: Directory for one LPAR.
- systems/<lpar-name>/cpus/<cpu-id>/: Directory for the virtual cpus
- systems/<lpar-name>/cpus/<cpu-id>/type: Typ of cpu.
- systems/<lpar-name>/cpus/<cpu-id>/mgmtime:
Accumulated number of microseconds during which a physical
CPU was assigned to the logical cpu and the cpu time was
consumed by the hypervisor and was not provided to
the LPAR (LPAR overhead).
- systems/<lpar-name>/cpus/<cpu-id>/cputime:
Accumulated number of microseconds during which a physical CPU
was assigned to the logical cpu and the cpu time was consumed
by the LPAR.
- systems/<lpar-name>/cpus/<cpu-id>/onlinetime:
Accumulated number of microseconds during which the logical CPU
has been online.
As mount point for the filesystem /sys/hypervisor/s390 is created.
The update process is triggered when writing 'something' into the
'update' file at the top level hypfs directory. You can do this e.g.
with 'echo 1 > update'. During the update the whole directory structure
is deleted and built up again.

Make swsusp allocate only as much memory as needed to store the image data
and metadata during resume.
Without this patch swsusp additionally allocates many page frames that will
conflict with the "original" locations of the image data and are considered
as "unsafe", treating them as "eaten" pages (ie. allocated but unusable).
The patch makes swsusp allocate as many pages as it'll need to store the
data read from the image in one shot, creating a list of allocated "safe"
pages, and use the observation that all pages allocated by it are marked
with the PG_nosave and PG_nosave_free flags set. Namely, when it's about
to load an image page, swsusp can check whether the page frame
corresponding to the "original" location of this page has been allocated
(ie. if the page frame has the PG_nosave and PG_nosave_free flags set) and
if so, it can load the page directly into this page frame. Otherwise it
uses an allocated "safe" page from the list to store the data that will be
copied to their "original" location later on.
This allows us to save many page copyings and page allocations during
resume and in the future it may allow us to load images greater than 50% of
the normal zone.
