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 ?
A simple google search should have answered this http://ohse.de/uwe/articles/gcc-attributes.html
Synopsis
regparm (NUMBER) Found in versions: 2.7-3.4 Description:
Functions that take a variable number of arguments will continue to be passed all of their arguments on the stack.
what does this mean?
