This series was clearing all of the selftests at the time it was posted.
But yes, it has some assumptions from timing and sync perspective which
gets broken some times as the kernel changes. Its been bit difficult to
perfect the sync requirements as we can do only some much inside the
transaction once it gets started. There are scopes here to improve these
selftests but not clearing them today does not really mean the patches are
now functionally broken.

hmm, sorry, I dont remember the context here. Can you please point to the
discussion in this regard ?

Can you please elaborate on this ? Has this patch been posted in the mailing
list ? How does this make it easier for us to implement these ELF notes ?
