• struct padata_list(9)
• struct padata_serial_queue(9)
• struct parallel_data(9)
• struct padata_shell(9)

• struct padata_instance(9)

go read them, i'll wait 🫶

ok that's the whole page bestie, it's a short one and honestly it ate 💀 no options, no flags, no danger, just two cpumasks being cute in ./include/linux.
