Prompted by the recent mails on ksummit, let's actually try to make this work this time. We need a container for manipulating strings easily, and seq_buf is the closest thing we have to it. The only problem I have with it is the readpos that is only useful for the tracing code today. So move it from the seq_buf to the tracing code.
We should go further with this patch series, including using seq_buf within vsprintf, but if we can't get over this hurdle first, I'm not going to waste my time on this again. v2: - Add [email protected] - Fix kernel-doc Matthew Wilcox (Oracle) (1): trace: Move readpos from seq_buf to trace_seq include/linux/seq_buf.h | 5 +---- include/linux/trace_seq.h | 2 ++ kernel/trace/trace.c | 10 +++++----- kernel/trace/trace_seq.c | 6 +++++- lib/seq_buf.c | 22 ++++++++++------------ 5 files changed, 23 insertions(+), 22 deletions(-) -- 2.40.1
