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.
