Date: Wed, 16 Sep 2015 11:08:40 +0200 From: Maurizio Lombardi <mlombard@...hat.com> To: tj@...nel.org Cc: joe@...ches.com, linux@...musvillemoes.dk, linux-kernel@...r.kernel.org 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 lib/vsprintf.c | 275 +++++++++++++++++++++++++++++++++++---------------------- 1 file changed, 167 insertions(+), 108 deletions(-) -- Maurizio Lombardi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
