What is the “current” in Linux kernel source?

Question

I\'m studying about Linux kernel and I have a problem.

I see many Linux kernel source files have current->files. So what is the current?

Answer 1

Current is a global variable of type struct task_struct. You can find it's definition at [1].

Files is a struct files_struct and it contains information of the files used by the current process.
