[Cluster-devel] [GIT PULL] dlm updates for 6.0

[Cluster-devel] [GIT PULL] dlm updates for 6.0

[David Teigland]

Hi Linus,

Please pull dlm updates from tag:

git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm.git dlm-6.0

Changes in this set of commits:

. Delay the cleanup of interrupted posix lock requests until the
  user space result arrives. Previously, the immediate cleanup
  would lead to extraneous warnings when the result arrived.

. Tracepoint improvements, e.g. adding the lock resource name.

. Delay the completion of lockspace creation until one full recove
  cycle has completed. This allows more error cases to be returned
  the caller.

. Remove warnings from the locking layer about delayed network rep
  The recently added midcomms warnings are much more useful.

. Begin the process of deprecating two unused lock-timeout-related
  features. These features now require enabling via a Kconfig opti
  and enabling them triggers deprecation warnings. We expect to
  remove the code in v6.2.

Thanks,
Dave

Gaah. That was the first thing I pulled this morning because it was
the earliest.

And apparently you've rebased, so I can't even just pull on top.

Gaah. Now I'll have to go back and re-do everything I've done this morning.

PLEASE don't do things like this to me. If you know you are going to
re-do a pull request, let me know early, so that I don't pull the old
one.

Very sorry about that.  (The obvious change there was updating the version
numbers in the deprecation messages to 6.2, and I should have just sent a
seprate patch to fix those up.)

At risk of compounding your trouble, I could have added that you can use
the original merge and have me send the fixup.

Well, I only had something like 4 other merges on top, none of them
*that* complicated.

And I hadn't pushed out, so I just redid them.

I did notice your "v2" pull request fairly quickly, because I try to
do my pulls (when I have lots of them, like at the beginning of the
merge window) in some kind of "order of areas", so I was doing
filesystem and vfs stuff, and  your v2 ended up showing up in that
bunch too, and I hadn't done too much.

I doubt I would have needed help with the conflicts, but I decided to
not even look at them, because even with them resolved it would just
have been ugly to have that pointless duplication from the rebase when
I could just start from scratch again.

But again: please don't rebase stuff you have already exposed to
others. It causes real issues. This was just one example of it.

And if you *do* have to rebase for a real technical reason ("Oh, that
was a disaster, it absolutely *must* be fixed"), please let involved
people know asap.

And a version number change is not a "huge disaster, must rebase".

Yep, thanks for the comments. For some reason this escaped the usual flags
that should have gone off in my head about rebasing.
