Hi Linus,
Were there any problems pulling from the xfs repository?
Thanks,
Felix

Sorry, no - just too much email, too many trees to look at, too many

Side note - I almost unpulled afterwards.
You've done several apparently totally useless pulls from my tree at
random points.
Daily "keep up-to-date with Linus' tree" pulls are _strongly_ discouraged
(read: if this continues, I'll just stop pulling from you), because it
makes the history totally unreadable after-the-fact. It has some direct
technical downsides (it makes it much harder to run "git bisect" and see
what is going on), but apart from those direct downsides it just makes it
much harder for me - or anybody else who wants to get an overview of what
happened - to visualize things when history is messy.
Instead of having a clear nice line of development that says "this is what
happened to XFS", those merges have basically mixed up all your changes
with all the random _other_ changes in the tree.
In other words, having those extra merges makes the graphical tools almost
useless for getting some kind of "what happened" overview.
I realize that an occasional back-merge may be required to resolve big
conflicts early, but they really have to be pretty big and immediate for
it to be a win.

That was my concern, i.e. it's not pulled without explicit
NAK. I knew about your possible concerns.

Yes, I noticed that, and agree with all your points even
before you brought them up.
I already started talking to people to improve my process.
The reason the intermediate pulls from your tree were done
is to make sure that new xfs patches would not conflict
with some other changes already in the mainline. That was
part of the maintainer cheat sheet given to me, and I
didn't realize the side effects of it.
I probably can verify the possible conflicts without pushing
the merges into the repository and reset the working tree to
pre pull state.
At any rate, I'll find some way to manage that without
cluttering the history with the merges.
Any suggestions are welcome.
Thanks,
Felix

create a temporary branch and do the merge in that. then throw away the
test branch and there is no harm to the main tree.

That was suggested among other things by Ingo Molnar as well.
I'm planing to follow this approach.

* XFS support for TRIM / blkdev_issue_discard?

Dear Felix Blyakher,
do you know whether there are plans to support the ATA TRIM command /
blkdev_issue_discard() call in XFS for Linux anytime soon?
I ask because as someone who is currently benchmarking solid state disks
for certain usage scenarios I noticed that other filesystems are starting
to support the discarding of unused blocks, which allows to prevent
performance-degradation of SSDs during heavy use.
(See e.g. http://www.mail-archive.com/cluster-devel@redhat.com/msg03401.html
on the GFS2 support for the discard feature, it seems not too hard
to implement the support)
Amongst other SSDs, we have one in our tests that supports the ATA TRIM command,
and I would like to test the benefits of it, even if that requires me
to install an early kernel pre-release.
(Currently, XFS is our favorite filesystem for several reasons, so it would
be great if we could run our TRIM-support-benchmarks using it)
Regards,
Peter Niemayer
