    The error variable breaks build on CentOS 6.7, due to collision with
    global error symbol:

    CC util/evlist.o
    cc1: warnings being treated as errors
    In file included from util/evlist.c:28:
    tools/include/linux/err.h: In function ‘ERR_PTR’:
    tools/include/linux/err.h:34: error: declaration of ‘error’ shadows a global declaration
    util/util.h:135: error: shadowed declaration is here

    Using 'error_' name instead to fix it.

    [ Use 'error_' instead of 'err' to, visually, not diverge too much from include/linux/err.h ]

  • 01ca9fd41   tools: Add err.h with ERR_PTR PTR_ERR interface ... Browse Code »

    Adding part of the kernel's interface:

    inline void * __must_check ERR_PTR(long error);
    inline long __must_check PTR_ERR(__force const void *ptr);
    inline bool __must_check IS_ERR(__force const void *ptr);

    It will be used to propagate error through pointers in following
    patches.
