thank you, this was very helpful. It's almost certainly:
- vfs: Make sendfile(2) killable even better
- vfs: Avoid softlockups with sendfile(2)
which are backports from Linux 4.4. OpenAFS had to disable splice() support to
be able to tolerate these changes. You need OpenAFS 1.6.18 or higher to obtain
relief for this, and indeed you did report that 1.6.18 is working fine for you
at this kernel level.
However, this does NOT explain your report of no problems with OpenAFS 1.6.17
and 1.6.16.
Could you please confirm that they are working fine?
