Greg Kroah-Hartman 0b79361ca0 staging: typec: remove redundant license text
Now that the SPDX tag is in all drivers/staging/typec/ files, that
identifies the license in a specific and legally-defined manner.  So the
extra GPL text wording can be removed as it is no longer needed at all.

This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text.  And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.

No copyright headers or other non-license-description text was removed.

Greg Kroah-Hartman 2ded45270a staging: typec: add SPDX identifier.
It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

Fix up the drivers/staging/typec/ files to have a proper SPDX
identifier, based on the license text in the file itself.  The SPDX
identifier is a legally binding shorthand, which can be used instead of
the full boiler plate text.

This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

'out' free's resources from the drvdata->ivgen_handle context.
However, drvdata->ivgen_handle has not been assigned to the

Fix this by setting drvdata->ivgen_handle to ivgen_ctx as early

As lnet wants to provide a cpu mask of allowed cpus, it

This patch also exported apply_workqueue_attrs() which is
a documented part of the workqueue API, that isn't currently

Several staging directories have TODO files that indicate a
subsystem will be removed in the future.

Using a status entry of "S:	Obsolete" helps indicate the
subsystem files should not be modified unnecessarily.

checkpatch also tests this setting and emits a warning that
the matching subsystem files should not be modified.

This might help avoid receiving patches that will be dropped.

NeilBrown 8d60ecd99c staging: lustre: replace LIBCFS_CPT_ALLOC()
LIBCFS_APT_ALLOC() calls kvmalloc_node() with GFP_NOFS
which is not permitted.
Mostly, a kmalloc_node(GFP_NOFS) is appropriate, though occasionally
the allocation is large and GFP_KERNEL is acceptable, so
kvmalloc_node() can be used.

This patch introduces 4 alternatives to LIBCFS_CPT_ALLOC():
 kmalloc_cpt()
 kzalloc_cpt()
 kvmalloc_cpt()
 kvzalloc_cpt().

Each takes a size, gfp flags, and cpt number.

Almost every call to LIBCFS_CPT_ALLOC() passes lnet_cpt_table()
as the table.  This patch embeds that choice in the k*alloc_cpt()
macros, and opencode kzalloc_node(..., cfs_cpt_spread_node(..))
in the one case that lnet_cpt_table() isn't used.

When LIBCFS_CPT_ALLOC() is replaced, the matching LIBCFS_FREE()
is also replaced, with with kfree() or kvfree() as appropriate.

NeilBrown 12e46c461c staging: lustre: change some LIBCFS_ALLOC calls to k?alloc(GFP_KERNEL)
When an allocation happens from process context rather than
filesystem context, it is best to use GFP_KERNEL rather than
LIBCFS_ALLOC() which always uses GFP_NOFS.
This include initialization during, or prior to, mount,
and code run from separate worker threads.

So for some of these cases, switch to kmalloc, kvmalloc, or
kvmalloc_array() as appropriate.
In some cases we preserve __GFP_ZERO (via kzalloc/kvzalloc), but in
others it is clear that allocated memory is immediately initialized.

In each case, the matching LIBCFS_FREE() is converted to
kfree() or kvfree()

This is just a subset of locations that need changing.
As there are quite a lot, I've broken them up into several
ad-hoc sets to avoid review-fatigue.

So it is much simpler to just allocate on the stack.
Worst case is lst_tet_add_ioct(), which allocates

NeilBrown 3c88bdbbf9 staging: lustre: replace simple cases of LIBCFS_ALLOC with kzalloc.
All usages of the form
  LIBCFS_ALLOC(variable, sizeof(variable))
or
  LIBCFS_ALLOC(variable, sizeof(variable's-type))

are changed to
  variable = kzalloc(sizeof(...), GFP_NOFS);

Similarly, all
   LIBCFS_FREE(variable, sizeof(variable))
become
   kfree(variable);

None of these need the vmalloc option, or any of the other minor
benefits of LIBCFS_ALLOC().
