Subsys_initcall_sync
Webinitcall_depend_t was decided in linker order as initcall itself did. When A is going to run, we can check if A would depend on others by checking the point indicate the current item in dependence table. If the field "call" of initcall_depend_t point to A, we know that A is depend on something and get Webinitcall机制的由来. 我们都知道，linux对驱动程序提供静态编译进内核和动态加载两种方式，当我们试图将一个驱动程序编译进内核时，开发者通常提供一个xxx_init ()函数接口以启动这个驱动程序同时提供某些服务。. 那么，根据常识来说，这个xxx_init ()函数肯定是 ...

Since now iommu_ops controls the group ownership, this takes it out of VFIO. This adds an IOMMU device into a pci_controller (=PHB) and registers it in the IOMMU subsystem, iommu_ops is registered at this point. This setup is done in postcore_initcall_sync.
Web7 Jan 2003 · Most of the work of porting devices drivers to the new model happens at the bus driver layer. This was intentional, to minimize the negative effect on kernel drivers, and to allow a gradual transition of bus drivers. In a nutshell, the driver model consists of a set of objects that can be embedded in larger, bus-specific objects.

WebIt is a function pointer that receives void parameters and returns int. This makes it clear. In fact, the first two sentences are just a test. When the parameters and return value of the function pointer you pass in are inconsistent with initcall_t, there will be an alarm. http://mamicode.com/info-detail-1278369.html
