Version 5!
Full diff between v4 and v5 will be replied to this email.
Here's the summary of the differences since version 4:
. Various clean ups
. Added trace_seq_used() to be used instead of s->seq.len
. Used seq_buf_used() instead of s->len
. Fixed output of ftrace_raw_output_prep() as well as caller code
. Fixed up tracing_fill_pipe_page() The logic was a bit whacky
and this was needed when introducing trace_seq_used()
. Rebased on latest ftrace/core code
. Fixed uprobe to be like probe code in print_uprobe_event()
. Introduced new seq_buf_can_fit() to remove the likelyhood of
screwing up the s->len + * < s->size code. Now it's just
seq_buf_can_fit(s, len) which will tell us if the len can still
fit in the buffer.
Enjoy,
