14 padata并行执行机制
23 据包进行加密和解密。这是目前padata的序列化作业支持的唯一用途。
33 使用padata执行序列化作业的第一步是建立一个padata_instance结构体，以全面
36 #include <linux/padata.h>
42 然后，通过分配一个padata_shell来完成padata的初始化::
46 一个padata_shell用于向padata提交一个作业，并允许一系列这样的作业被独立地
75 含用户提供的掩码中的在线CPU；这些是padata实际使用的cpumasks。因此，向padata提
77 padata就会使用它。
84 实际上向padata实例提交工作需要创建一个padata_priv结构体，它代表一个作业::

Dpadata.rst4 The padata parallel execution mechanism
14 is currently the sole consumer of padata's serialized job support.
25 The first step in using padata to run serialized jobs is to set up a
28 #include <linux/padata.h>
34 Then, complete padata initialization by allocating a padata_shell::
38 A padata_shell is used to submit a job to padata and allows a series of such
72 user-supplied masks; these are the cpumasks padata actually uses. So it is
73 legal to supply a cpumask to padata that contains offline CPUs. Once an
74 offline CPU in the user-supplied cpumask comes online, padata is going to use
83 Actually submitting work to the padata instance requires the creation of a
