   # HEAD: 90dfeef1cd38dff19f8b3a752d13bfd79f0f7694 seqlock: Cure some more scoped_seqlock() optimization fails

Two fixes related to recent introduction of scoped_seqlock_read():

 - Fix compiler build failures when a particular .config and
   compiler build options variant doesn't result in the
   expected removal of unused, catch-bugs portions of
   scoped_seqlock_read() by the inliner at build time,
   and cause a linker fail even in correct code.

 - Match read-locking order in do_task_stat() and
   do_io_accounting(). The inconsistency here was harmless
   but unnecessary.

 Thanks,

	Ingo
