This is probably not a regression. See this earlier discussion:
http://lkml.org/lkml/2010/1/15/76
And another report, coincidentally at the same time:
http://lkml.org/lkml/2010/1/18/108
As I understand Christoph's post on January 19, several code paths are
independently affected:
http://lkml.org/lkml/2010/1/19/267
(Maybe some of those have been fixed in the meantime.)
I don't see in my trace from September 1 which filesystem caused the
particular lockdep report. I may have unmounted ext4, vfat, or fuse prior to
that.

Is it feasible to add a gfp_flag argument to all call chains that could lead
to allocations in unmount?

I think this should not be marked as a regression. See the older reports of
very similar issues (in my LKML mail from September 3, logged in bugzilla in
comment #1)
http://lkml.org/lkml/2010/1/15/76 (2.6.33-rc, xfs involved)
http://lkml.org/lkml/2010/1/18/108 (2.6.32.y, ntfs involved)
and hch's analysis in the first of these two threads
http://lkml.org/lkml/2010/1/19/267 (several filesystems and
other code paths)
So, unless my trace was a code path that only newly acquired that oldproblem
of other code paths, this is an older issue. Alas this is not obvious to me
at least from the log that I got.
I did not have lockdep enabled on the machine which delivered the log during
the last few months or so; I just remembered to re-enable it at the occasion
of switching to 2.6.36-rc.

Thanks a lot for the info, I've dropped this bug from the list of recent regressions.
