    include, lib: add __printf attributes to several function prototypes · 8db14860
    Nicolas Iooss 提交于
    Using __printf attributes helps to detect several format string issues
    at compile time (even though -Wformat-security is currently disabled in
    Makefile).  For example it can detect when formatting a pointer as a
    number, like the issue fixed in commit a3fa71c4 ("wl18xx: show
    rx_frames_per_rates as an array as it really is"), or when the arguments
    do not match the format string, c.f.  for example commit 5ce1aca8
    ("reiserfs: fix __RASSERT format string").
    
    To prevent similar bugs in the future, add a __printf attribute to every
    function prototype which needs one in include/linux/ and lib/.  These
    functions were mostly found by using gcc's -Wsuggest-attribute=format
    flag.
