Port the xattr functionality to the new xattr_handler API. This is smallest changes needed to move to this new API. The function ll_removexattr can be replaced by generic_removexattr as well since it also uses the xattr_handler set xattr backend. To tell the difference between the two cases we test the flag passed in for XATTR_REPLACE. The ll_getxattr function is replaced by the generic_getxattr function.

Split the function ll_getxattr_common into two functions. The code used for listing xattrs and ll_getxattr_common is placed into a new function ll_getxattr_list. This allows ll_listxattr to call directly ll_getxattr_list instead of going through ll_getxattr_common. This change is needed for the upcoming VFS move xattr_handler from [s|g]etxattr.

Bhaktipriya Shridhar authored
The workqueue is being used to run deferred work for the android binder. The "binder_deferred_workqueue" queues only a single work item and hence does not require ordering. Also, this workqueue is not being used on a memory recliam path. Hence, the singlethreaded workqueue has been replaced with the use of system_wq. System workqueues have been able to handle high level of concurrency for a long time now and hence it's not required to have a singlethreaded workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue created with create_singlethread_workqueue(), system_wq allows multiple work items to overlap executions even on the same CPU; however, a per-cpu workqueue doesn't have any CPU locality or global ordering guarantee unless the target CPU is explicitly specified and thus the increase of local concurrency shouldn't make any difference.

SW_SYNC allows to run tests on the sync_file framework via debugfs on <debugfs>/sync/sw_sync Opening and closing the file triggers creation and release of a sync timeline. To create fences on this timeline the SW_SYNC_IOC_CREATE_FENCE ioctl should be used. To increment the timeline value use SW_SYNC_IOC_INC.
