devres: Use kmalloc_size_roundup() to match ksize() usage

2022-11-09T14:11:46Z

Round up allocations with kmalloc_size_roundup() so that devres's use of ksize() is always accurate and no special handling of the memory is needed by KASAN, UBSAN_BOUNDS, nor FORTIFY_SOURCE.

devres: Slightly optimize alloc_dr()

2022-09-01T16:17:14Z

If the gfp flag used for the memory allocation already has __GFP_ZERO, then there is no need to explicitly clear the "struct devres_node". It is already zeroed. This saves a few cycles when using devm_zalloc() and co. In the case of devres_alloc() (which calls __devres_alloc_node()), the compiler could remove the test and the memset() because it should be able to see that the __GFP_ZERO flag is set. So this would make the code both faster and smaller.

devres: Enable trace events

2021-06-15T15:14:36Z

In some cases the printf() mechanism is too heavy and can't be used. For example, when debugging a race condition involving devres API. When CONFIG_DEBUG_DEVRES is enabled I can't reproduce an issue, and otherwise it's quite visible with a useful information being collected. Enable trace events for devres part of the driver core.

devres: Use list_for_each_safe_from() in remove_nodes()

The remove_nodes() open codes the list_for_each_safe_from(). Replace it by a generic macro. Signed-off-by: Andy Shevchenko Link: https://lore.kernel.org/r/20210517122946.53161-2-andriy.shevchenko@linux.intel.com Signed-off-by: Greg Kroah-Hartman

devres: Make locking straight forward in release_nodes()

2021-06-15T15:14:36Z

It seems for the sake of saving stack memory of couple of pointers, the locking in release_nodes() callers becomes interesting. Replace this logic with a straight forward locking and unlocking scheme.

class_create is actually defined at the header. Fix the markup there and add a new one at the right place. While here, also fix some markups for functions that have different names between their prototypes and kernel-doc comments.
