What is "__attribute__()" in kernel code

[sandeep kumar]

Hi all,

I was wondering what __attribute__ does in the kernel code?
I found several definitions but couldnot come to one conclusion..

__releases(x)  is defined in compiler.h. What does this mean??
# define __releases(x)                  __attribute__((context(x,1,0)))
Thanking you
