      "message": "syscalls, x86: add __NR_kcmp syscall\n\nWhile doing the checkpoint-restore in the user space one need to determine\nwhether various kernel objects (like mm_struct-s of file_struct-s) are\nshared between tasks and restore this state.\n\nThe 2nd step can be solved by using appropriate CLONE_ flags and the\nunshare syscall, while there\u0027s currently no ways for solving the 1st one.\n\nOne of the ways for checking whether two tasks share e.g.  mm_struct is to\nprovide some mm_struct ID of a task to its proc file, but showing such\ninfo considered to be not that good for security reasons.\n\nThus after some debates we end up in conclusion that using that named\n\u0027comparison\u0027 syscall might be the best candidate.  So here is it --\n__NR_kcmp.\n\nIt takes up to 5 arguments - the pids of the two tasks (which\ncharacteristics should be compared), the comparison type and (in case of\ncomparison of files) two file descriptors.\n\nLookups for pids are done in the caller\u0027s PID namespace only.\n\nAt moment only x86 is supported and tested.\n\n[akpm@linux-foundation.org: fix up selftests, warnings]\n[akpm@linux-foundation.org: include errno.h]\n[akpm@linux-foundation.org: tweak comment text]\nSigned-off-by: Cyrill Gorcunov \u003cgorcunov@openvz.org\u003e\nAcked-by: \"Eric W.
