devres: Add devm_get_free_pages API

2014-05-23T17:19:25Z

devm_get_free_pages() and devm_free_pages() are the managed counterparts for __get_free_pages() and free_pages(). Signed-off-by: Eli Billauer Acked-by: Tejun Heo Signed-off-by: Greg Kroah-Hartman

devres: introduce API "devm_kmemdup

2014-04-29T20:58:15Z

Introduce devm_kmemdup, which uses resource managed kmalloc. There are several request from maintainers to add this instead of using kmemdup. Signed-off-by: Srinivas Pandruvada Signed-off-by: Jonathan Cameron

devres: introduce API "devm_kstrdup"

2014-02-11T16:34:32Z

This patch introduces "devm_kstrdup" API so that the device's driver can allocate memory and copy string. Signed-off-by: Manish Badarkhe Signed-off-by: Mark Brown

devres: restore zeroing behavior of devres_alloc()

2013-10-25T04:46:27Z

commit 64c862a8 (devres: add kernel standard devm_k.alloc functions) changed the default behavior of alloc_dr() to no longer zero the allocated memory. However, only the devm.k.alloc() function were modified to pass in __GFP_ZERO which leaves any users of devres_alloc() or __devres_alloc() with potentially wrong assumptions about memory being zero'd upon allocation. To fix, add __GFP_ZERO to devres_alloc() calls to preserve previous behavior of zero'ing memory upon allocation.

devres: add kernel standard devm_k.alloc functions

2013-10-17T01:29:07Z

Currently, devm_ managed memory only supports kzalloc. Convert the devm_kzalloc implementation to devm_kmalloc and remove the complete memset to 0 but still set the initial struct devres header and whatever padding before data to 0. Add the other normal alloc variants as static inlines with __GFP_ZERO added to the gfp flag where appropriate: devm_kzalloc devm_kcalloc devm_kmalloc_array Add gfp.h to device.h for the newly added static inlines. akpm: the current API forces us to replace kmalloc() with kzalloc() when performing devm_ conversions. This adds a relatively minor overhead. More significantly, it will defeat kmemcheck used-uninitialized checking, and for a particular driver, losing used-uninitialised checking for their core controlling data structures will significantly degrade kmemcheck usefulness.

Merge tag 'v3.9-rc3' into next

2013-03-18T02:40:50Z

Merge with mainline to bring in module_platform_driver_probe() and devm_ioremap_resource().

devres: allow adding custom actions to the stack

2013-02-26T07:02:42Z

Sometimes drivers need to execute one-off actions in their error handling or device teardown paths. An example would be toggling a GPIO line to reset the controlled device into predefined state. To allow performing such actions when using managed resources let's allow adding them to stack/group of devres resources.

drivers: base: Convert dev_printk(KERN_ to dev_(

2012-10-31T00:38:43Z

dev_ calls take less code than dev_printk(KERN_ and reducing object size is good. Signed-off-by: Joe Perches Signed-off-by: Greg Kroah-Hartman

driver core: devres: introduce devres_for_each_res

2012-08-16T20:30:29Z

This patch introduces one devres API of devres_for_each_res so that the device's driver can iterate each resource it has interest in. The firmware loader will use the API to get each firmware name from the device instance. Signed-off-by: Ming Lei Cc: Linus Torvalds Signed-off-by: Greg Kroah-Hartman

devres: Add devres_release()

2012-05-04T23:33:16Z

APIs using devres frequently want to implement a "remove and free the resource" operation so it seems sensible that they should be able to just have devres do the freeing for them since that's a big part of what devres is all about. Signed-off-by: Mark Brown Signed-off-by: Greg Kroah-Hartman
