dccp_init() is never called in atomic context.
This function is only set as a parameter of module_init().
Despite never getting called from atomic context,
dccp_init() calls __get_free_pages() with GFP_ATOMIC,

What do you mean by "waits busily" ?
GFP_ATOMIC does not sleep, does not wait.

Do you think it is okay?
Best wishes,
