crypto: pcrypt - Update pcrypt cpumask according to the padata cpumask notifier

2010-07-31T11:53:06+00:00

The padata cpumask change notifier passes a padata_cpumask to the
notifier chain. So we use this cpumask instead of asking padata for
the cpumask.

crypto: pcrypt - Rename pcrypt_instance

2010-07-31T11:53:05+00:00

In the crypto-layer an instance refers usually to a crypto instance.
The struct pcrypt_instance is not related to a crypto instance.
It rather contains the padata informations, so we rename it to
padata_pcrypt. The functions that handle this struct are renamed
accordingly.

padata: Rename padata_alloc functions

2010-07-31T11:53:04+00:00

We rename padata_alloc to padata_alloc_possible because this
function allocates a padata_instance and uses the cpu_possible
mask for parallel and serial workers. Also we rename __padata_alloc
to padata_alloc to avoid to export underlined functions. Underlined
functions are considered to be private to padata. Users are updated
accordingly.

crypto: pcrypt - Dont calulate a callback cpu on empty callback cpumask

2010-07-26T06:13:59+00:00

If the callback cpumask is empty, we crash with a division by zero
when we try to calculate a callback cpu. So we don't update the callback
cpu in pcrypt_do_parallel if the callback cpumask is empty.

pcrypt: Added sysfs interface to pcrypt

2010-07-19T05:50:20+00:00

Added sysfs interface to pcrypt. Now pcrypt subsystem creates two
sysfs directories with corresponding padata sysfs objects:
 /sys/kernel/pcrypt/[pencrypt|pdecrypt]

padata: Make two separate cpumasks

2010-07-19T05:50:19+00:00

The aim of this patch is to make two separate cpumasks
for padata parallel and serial workers respectively.
It allows user to make more thin and sophisticated configurations
of padata framework. For example user may bind parallel and serial workers to non-intersecting
CPU groups to gain better performance. Also each padata instance has notifiers chain for its
cpumasks now. If either parallel or serial or both masks were changed all
interested subsystems will get notification about that. It's especially useful
if padata user uses algorithm for callback CPU selection according to serial cpumask.

padata: make padata_do_parallel to return zero on success

2010-07-14T12:29:29+00:00

To return -EINPROGRESS on success in padata_do_parallel was
considered to be odd. This patch changes this to return zero
on success. Also the only user of padata, pcrypt is adapted to
convert a return of zero to -EINPROGRESS within the crypto layer.
This also removes the pcrypt fallback if padata_do_parallel
was called on a not running padata instance as we can't handle it
anymore. This fallback was unused, so it's save to remove it.

padata: Check for valid padata instance on start

2010-07-14T12:29:28+00:00

This patch introduces the PADATA_INVALID flag which is
checked on padata start. This will be used to mark a padata
instance as invalid, if the padata cpumask does not intersect
with the active cpumask. we change padata_start to return an
error if the PADATA_INVALID is set. Also we adapt the only
padata user, pcrypt to this change.
