The LSM_AUDIT_DATA_* records for PATH, FILE, IOCTL_OP, DENTRY and INODE are incomplete without the task context of the AUDIT Current Working Directory record. Add it. This record addition can't use audit_dummy_context to determine whether or not to store the record information since the LSM_AUDIT_DATA_* records are initiated by various LSMs independent of any audit rules. context->in_syscall is used to determine if it was called in user context like audit_getname.
