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