dma-buf/sw-sync: Remove unused debug code

2025-05-08T10:51:59+00:00

sync_file_debug_add() and sync_file_debug_remove() have been unused since 2016's commit d4cab38e153d ("staging/android: prepare sync_file for de-staging") Remove them. Since sync_file_debug_add was the only thing to add to sync_file_list_head, the code that dumps it in part of sync_info_debugfs_show can be removed, and the declaration of the list and it's associated lock can be removed. (The 'fences:\n...' marker in that debugfs file is left in so as not to change the output) That leaves the sync_print_sync_file() helper unused, and is thus removed.

dma-buf/dma-fence: remove unnecessary callbacks

2025-03-06T14:20:53+00:00

The fence_value_str and timeline_value_str callbacks were just an unnecessary abstraction in the SW sync implementation. The only caller of those callbacks already knew that the fence in questions is a timeline_fence. So print the values directly instead of using a redirection. Additional to that remove the implementations from virtgpu and vgem. As far as I can see those were never used in the first place.

dma-buf/sw-sync: don't enable IRQ from sync_print_obj()

2024-05-24T14:30:05+00:00

Since commit a6aa8fca4d79 ("dma-buf/sw-sync: Reduce irqsave/irqrestore from known context") by error replaced spin_unlock_irqrestore() with spin_unlock_irq() for both sync_debugfs_show() and sync_print_obj() despite sync_print_obj() is called from sync_debugfs_show(), lockdep complains inconsistent lock state warning. Use plain spin_{lock,unlock}() for sync_print_obj(), for sync_debugfs_show() is already using spin_{lock,unlock}_irq().
