H A Dpadata.rst42 Modifying cpumasks
57 There may be sysfs files for an instance's cpumasks. For example, pcrypt's
67 Padata maintains two pairs of cpumasks internally, the user-supplied cpumasks
68 and the 'usable' cpumasks. (Each pair consists of a parallel and a serial
69 cpumask.) The user-supplied cpumasks default to all possible CPUs on instance
70 allocation and may be changed as above. The usable cpumasks are always a
71 subset of the user-supplied cpumasks and contain only the online CPUs in the
72 user-supplied masks; these are the cpumasks padata actually uses. So it is
111 serial cpumask, no online CPUs in the parallel or serial cpumasks, or a stopped
