=3D=3D Linux news =3D=3D

Marc tested with the current mainline, no need for changes yet.

=3D=3D 1.6.7 changes pre announcements =3D=3D

Last week, we decided to make 1.6.7+ clients give up their callbacks on =
shutdown, causing problems for older fileservers in the 1.3.50 - 1.4.5 =
and 1.5.0 - 1.5.27 ranges, without a knob to turn this off, and that =
this
should be announced in advance on the -info and -announce lists as well =
as at EAKC. It just wasn't defined who will do it, and when. Postponed =
to a meeting with Jeffrey present, since it was his proposal.

Stephan proposes including the planned fileserver change to =
-sync=3Donclose in these announcements.

Andrew's summary:

It was seen via discussion (with Jason/Stephan) that the 130273 issue is
relevant for new RHEL5 updates, as well as RHEL6. RHEL7 is not affected
yet, but that could change. Andrew is to get a little more information
and reproduce the relevant scenarios and we'll talk about this next
week. Andrew may try to bring the "bind-mount" implementation up to
speed if he has time.


=3D=3D Status of other items foreseen for 1.6.7 =3D=3D

Marc's patch for the Linux getcwd ENOENT problem (see RT #131780 and =
references therein), gerrit 10804, was merged during the meeting. As =
well as 10598 which hadn't quite made 1.6.6. And a few others were =
merged or reviewed sufficiently to be merged once their dependencies =
are.

Stephan complains about there being too many path conflicts between =
changes pulled up for 1.6 in gerrit already, and asks to not add more.


[the remainder of this text is 1.6.7 bookeeping]

Idledead change to help the "no buffer space available" problem: Gerrit =
10773 ist still being reviewed on master, blocked on two trivial changes =
to be done.

Parallel build fixes =
(http://gerrit.openafs.org/#q,project:openafs+branch:master+topic:parallel=
-make,n,z ). No progress.
