The percpu counter data type are changed in this set of patches to support
more users like ext3 who need more than 32 bit to store the free blocks
total in the filesystem.
- Generic perpcu counters data type changes. The size of the global counter
and local counter were explictly specified using s64 and s32. The global
counter is changed from long to s64, while the local counter is changed from
long to s32, so we could avoid doing 64 bit update in most cases.
- Users of the percpu counters are updated to make use of the new
percpu_counter_init() routine now taking an additional parameter to allow
users to pass the initial value of the global counter.

Here's a patch for cs46xx that
- (mostly) cleans up the cs46xx driver according to CodingStyle
- removes a bunch of pointless casts
- fixes a small, potential use of uninitialized variable, bug
- reduces the size of the compiled code by 36 bytes
- reduces the size of the source file by 1831 bytes
I know I should probably have split this into bits, but since I only
thought of that *after* doing all the edits, splitting it up would have
been a royal pain. And since these are all pretty trivial changes I thought
I'd just submit the one huge patch and hope people could live with it (if
not, then just tell me and I'll split it).
The bug fix that's in there may be hard to spot, so I'll point it out. It's
the
- int val, valsave, mapped, ret;
+ int val, valsave, ret;
+ int mapped = 0;
bit.
Without that change we may use `mapped' uninitialized if, in cs_ioctl, the
first test of "if(state)" is false and the second "if(state)" test is true.

Fix possible assertion failure in journal_commit_transaction() on
jh->b_next_transaction == NULL (when we are processing BJ_Forget list and
buffer is not jbddirty).
!jbddirty buffers can be placed on BJ_Forget list for example by
journal_forget() or by __dispose_buffer() - generally such buffer means
that it has been freed by this transaction.
Freed buffers should not be reallocated until the transaction has committed
(that's why we have the assertion there) but they *can* be reallocated when
the transaction has already been committed to disk and we are just
processing the BJ_Forget list (as soon as we remove b_committed_data from
the bitmap bh, ext3 will be able to reallocate buffers freed by the
committing transaction). So we have to also count with the case that the
buffer has been reallocated and b_next_transaction has been already set.
And one more subtle point: it can happen that we manage to reallocate the
buffer and also mark it jbddirty. Then we also add the freed buffer to the
checkpoint list of the committing trasaction. But that should do no harm.
Non-jbddirty buffers should be filed to BJ_Reserved and not BJ_Metadata
list. It can actually happen that we refile such buffers during the commit
phase when we reallocate in the running transaction blocks deleted in
committing transaction (and that can happen if the committing transaction
already wrote all the data and is just cleaning up BJ_Forget list).

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() 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.
