 We need to call this function to eliminate potential leak of the execve'd binary's [file descriptor](https://en.wikipedia.org/wiki/File_descriptor). In the next step we start preparation of the `bprm` that represented by the `struct linux_binprm` structure (defined in the [include/linux/binfmts.h](https://github.com/torvalds/linux/blob/master/linux/binfmts.h) header file). The `linux_binprm` structure is used to hold the arguments that are used when loading binaries. For example it contains `vma` field which has `vm_area_struct` type and represents single memory area over a contiguous interval in a given address space where our application will be loaded, `mm` field which is memory descriptor of the binary, pointer to the top of memory and many other different fields.
