Some fields have been added into linux 3.7 tracepoints, and the order of some other fields are realigned to increase data density (avoid holes because of alignment).

The only thing that needed a sync is a1ce392 that fixes includes, and there is no consequence on lttng-modules (includes were already global instead of relative).

The following patch is only for completeness and avoid any diff with mainline headers.

Besides this patch, are there other changes that are needed on the master branch to be in line with 3.7 ?

There are missing events in lttng according to mainline:

  • 9p.h : Plan 9 Filesystem Protocol
  • mce.h : Machine check handler
  • migrate.h : trace_mm_migrate_pages
  • oom.h : trace_oom_score_adj_update
  • task.h : task_newtask and task_rename: replaces clone/exec syscall for analysis
  • xen.h : XEN tracepoints

It depends whether we want to support those.
