Okay, I posted four patches on 5th July: https://lore.kernel.org/lkml/153080826773.5496.7106875523806885716.stgit@xxxxxxxxxxxxxxxxxxxxxx/ These five patches are the same aggregate changes, just with the first patch split and a description composed for both parts: warthog>git diff fscache-fixes-20180705 fscache-fixes-20180725 warthog> The patch series as a whole got tested by Scott Mayhew whilst seeing if they cured a bug he was looking at: https://marc.info/?l=linux-nfs&m=153191593807248&w=2 I've also ported them to RHEL-7 where they've undergone some automated testing with iozone.
