    8.10 -    Implement kasprintf, a kernel version of asprintf.  This allocates the
    8.11 -    memory required for the formatted string, including the trailing '\0'.
    8.12 -    Returns NULL on allocation failure.

    23.8 -    [PATCH] Fix bounds check in vsnprintf, to allow for a 0 size and NULL buffer
    23.9 -    
   23.10 -    This change allows callers to use a 0-byte buffer and a NULL buffer pointer
   23.11 -    with vsnprintf, so it can be used to determine how large the resulting
   23.12 -    formatted string will be.
   23.13 -    
   23.14 -    Previously the code effectively treated a size of 0 as a size of 4G (on
   23.15 -    32-bit systems), with other checks preventing it from actually trying to
   23.16 -    emit the string - but the terminal \0 would still be written, which would
   23.17 -    crash if the buffer is NULL.
   23.18 -    
   23.19 -    This change changes the boundary check so that 'end' points to the putative
   23.20 -    location of the terminal '\0', which is only written if size > 0.
   23.21 -    
   23.22 -    vsnprintf still allows the buffer size to be set very large, to allow
   23.23 -    unbounded buffer sizes (to implement sprintf, etc).

    36.8 +    [PATCH] Implement kasprintf
    36.9 +    
   36.10 +    Implement kasprintf, a kernel version of asprintf.  This allocates the
   36.11 +    memory required for the formatted string, including the trailing '\0'.
   36.12 +    Returns NULL on allocation failure.
