| |
This is an RFC patch set. The trace_seq currently has its buffer within the structure itself. But this limits its ability and efficiency.
This patch set separates it out, but now it requires the callers to supply their own buffer. But this helps out the splice code because it can now write directly into the splice pages.
This may be too much for 33? But it is a nice fix.
Thoughs?
The following patches are in:
