[PATCH 0/7] tracing: seqfile fixes, take 2

[Li Zefan]

While testing syscall tracepoints proposed by Jason, I found some
entries were missing when reading available_events.

It turned out there's bug in seqfile handling. The bug is, it's
wrong to increment @pos in seq start().

The bug exists in some other places. I also fixed some other different
bugs.

All the patches have been reviewed and tested.

Thanks Liming Wang for the review.
