The first thing it must do is look up the VMA corresponding to the address that was passed - if the passed address was within the kernel's address range, then there is no VMA, and so this search will fail. Like mprotect(), pkey_mprotect() changes the protection on the pages specified by addr and len. The pkey argument specifies the protection key (see pkeys(7)) to assign to the memory.

Legitimate values for prot are the same as those permitted for mprotect() and are defined in : PROT_READ page can be read PROT_WRITE page can be mprotect() changes protection for the calling process's memory page(s) containing any part of the address range in the interval [addr, addr+len-1]. addr must be aligned to a page boundary. If the calling process tries to access memory in a manner that violates the protection, then the kernel generates a SIGSEGV signal for the process.

In standard C, the only portable arguments to exit() are 0, EXIT_SUCCESS, and EXIT_FAILURE. If you're not concerned with portability to all C implementations (and since you're using mprotect(), presumably you're not), you can use other values, but errno values aren't necessarily sensible.
