*grumble*
OK, with atomic_open series in there (and stomping all over NFS)
I should have expected that kind of thing (i.e. another subsystem
tree doing pulls from vfs.git). Mea culpa...
FWIW, I've got used to folding fixes back into the offending commits;
that has the same effect as rebase, as far as the trees that pull
from vfs.git are concerned. Sigh... Guess I'll do s/.*/&-rebased-at-will/
for branches in there and if somebody needs a stable one, create it
on demand (and yes, this time around it was clearly going to be needed;
again, my apologies for missing that)
OK, I've grabbed nfs tree. The only real issue was the fixup folded
into one commit in the set they've got....
I think the least painful solution is this: I've created a new branch
(for-linus-2) in there, growing off the parent of merge in nfs.git.
I've put the fixup to kern_path_locked() there as a separate commit
+ stuff that went in for-linus after that point.
Result: for-linus-2 + v3.5 and for-linus + v3.5 give identical trees,
and for-linus-2 merges clean with nfs/nfs-for-3.6. Would you be OK
with pulling that one? Again, my apologies to everyone involved ;-/
If you are OK with pulling that one, the summary is unchanged, location is
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git for-linus-2
