[RFC PATCH 0/3] fix *pbl format support

[Maurizio Lombardi <mlombard@redhat.com>]

Hi,

I tried to fix the "*pb[l]" format issue while taking care of the problems
discussed in this thread:

https://lkml.org/lkml/2015/9/9/153

I would like to know whether this approach is more acceptable to you:

PATCH 1 modifies the code so that the printf_spec struct is not passed by value
anymore, instead a const pointer is used and the structure is copied to
a local variable only when necessary.

PATCH 2 modifies the bitmap_*_string() functions so they'll append "..." to the
output string whenever the buffer is not sufficiently large.

example of output:

*pb: cccccccc,...
*pbl: 1-2,5-7,...

PATCH 3 increases the size of printf_spec.field_width (from s16 to s32).

Maurizio Lombardi (3):
  lib/vsprintf.c: Do not pass printf_spec by value on stack.
  lib/vsprintf.c: append "..." if the *pb[l] output has been truncated.
  lib/vsprintf.c: increase the size of the field_width variable
