drm: Introduce drm_property_blob_{get,put}()

2017-02-28T15:16:46+00:00

For consistency with other reference counting APIs in the kernel, add
drm_property_blob_get() and drm_property_blob_put() to reference count
DRM blob properties.

Compatibility aliases are added to keep existing code working. To help
speed up the transition, all the instances of the old functions in the
DRM core are already replaced in this commit.

A semantic patch is provided that can be used to convert all drivers to
the new helpers.

drm: Introduce drm_gem_object_{get,put}()

2017-02-28T15:16:43+00:00

For consistency with other reference counting APIs in the kernel, add
drm_gem_object_get() and drm_gem_object_put(), as well as an unlocked
variant of the latter, to reference count GEM buffer objects.

Compatibility aliases are added to keep existing code working. To help

The existing semantic patch for the DRM subsystem-wide conversion is
extended to account for these new helpers.

Coccinelle: pm_runtime: ensure relevance of pm_runtime reports

2016-10-01T21:03:41+00:00

pm_runtime.cocci starts with one rule that searches for a variety of
functions calls, followed by various rules that report errors.  Previously,
the only connection between the first rule and the rest was to check that
the first rule had matched somewhere.  Change the rules to propagate a
position from the first rule to the others, to make sure that the sites
reported on are the same as the sites that were identified as having the
relevant functions.

Coccinelle: limit memdup_user transformation to GFP_KERNEL case

2016-10-01T21:03:09+00:00

Memdup_user encapsulates a memory allocation with the flag GFP_KERNEL, so
only allow this flag in the original code.

Add space in front of the offending parentheses to silent the
parse error for older Coccinelle versions. This makes the rule
usable with all Coccinelle versions.

debugfs, coccinelle: check for obsolete DEFINE_SIMPLE_ATTRIBUTE() usage

2016-04-12T21:14:21+00:00

In order to protect against file removal races, debugfs files created via
debugfs_create_file() now get wrapped by a struct file_operations at their
opening.

If the original struct file_operations are known to be safe against removal
races by themselves already, the proxy creation may be bypassed by creating
the files through debugfs_create_file_unsafe().

In order to help debugfs users who use the common
  DEFINE_SIMPLE_ATTRIBUTE() + debugfs_create_file()
idiom to transition to removal safe struct file_operations, the helper
macro DEFINE_DEBUGFS_ATTRIBUTE() has been introduced.

Thus, the preferred strategy is to use
  DEFINE_DEBUGFS_ATTRIBUTE() + debugfs_create_file_unsafe()
now.

Introduce a Coccinelle script that searches for
DEFINE_SIMPLE_ATTRIBUTE()-defined struct file_operations handed into
debugfs_create_file(). Suggest to turn these usages into the
  DEFINE_DEBUGFS_ATTRIBUTE() + debugfs_create_file_unsafe()
pattern.
