# 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
