ksys_unshare | share allows a process to 'unshare' part of the process* context which was originally shared using clone. copy_** functions used by do_fork() cannot be used here directly* because they modify an inactive task_struct that is being* constructed |
unshare_files | Helper to unshare the files of the current task.* We don't want to expose copy_files internals to* the exec layer of the kernel. |
