Thanks for the report!  I'll note that it's fixed in sid, and leave the
bug open pending a backport to jessie.  (People interested in a backport
to wheezy as well should speak up -- though the backport should not be
difficult, it is helpful to justify the upload when there is user demand.)

Bug#831751: openafs-client unreliable after kernel update

2016-07-18 Thread Chad Seys 
Package: openafs-client
Version: 1.6.9-2+deb8u5
Severity: important

Dear Maintainer,

As discussed on the openafs-info mailing list, the openafs-client is unreliable 
(cannot checkout certain repos) after some backported patches were applied to 
the
kernel.

With respect to the 'git checkout test' was when openafs-client
is paired with 
  3.16.7-ckt20-1+deb8u4
and first broken is
  3.16.7-ckt25-1
.

Mark Vitale suspects that these changes are responsible for the breakage:
   - vfs: Make sendfile(2) killable even better
   - vfs: Avoid softlockups with sendfile(2)

Also note that openafs packages for Debian versions 1.6.17 and 1.6.18 do not 
fail
the 'git checkout test' with recent Jessie kernel.

This link is to the thread on openafs-info in which Jonathan Kollasch, Benjamin 
Kaduk,
Jeffry Altman, and Mark Vitale helped focus debugging on the relavant facts.  
Thanks
all!
