hi:

In kernel code . some function is defined by

__attribute__((__section__(".initcall" level ".init")))

...

what does this do ?

It puts the address of the function in a linker section named .initcallX.init where X is replaced by the level.

These functions are called in order to initialize various subsystems and drivers during kernel bootup.

Thanks! Another question: __attribute__((regparm(3))) ; what does this do ?
