disk space caching generation missmatch

After enabling disk space caching I''ve observed several log entries
like this:

btrfs: free space inode generation (0) did not match free space cache generation
(169594) for block group 15464398848

I''m not sure, but it seems this happens on every reboot. Is this
something to
worry about?

regards,
  Johannes

So that usually means 1 of a couple of things

1) You didn''t have space for us to save the free space cache
2) When trying to write out the cache we hit one of those cases where we would
deadlock so we couldn''t write the cache out

It''s nothing to worry about, it''s doing what it is supposed
to.  However I''d
like to know why we''re not able to write out the cache.  Are you
running close
to full?  Thanks,

Josef

I think there should be enough free space:

Hmm well then we''re hitting one of the other corner cases.  Can you run
with
this debug thread and reboot.  Hopefully it will tell me why we''re not
saving
the free space cache. Thanks,

Josef

Ok it doesn''t look like theres an actual problem, we''re just
being sub-optimal.
Take out the other patch and apply this one, boot into that kernel and then
reboot and then give me the dmesg.  The thing is we are marking non-cached block
groups as being setup, but they really aren''t, so we error out when we
try to
write out the block group.  This isn''t wrong, it''s just crappy
since we know we
wont be able to write the things out anyway.  So just mark the thing as written
so we dont even try.  The other cases appear to be where the block group is
empty, so we dont need to write anything out, but because of where I have the
check it makes it seem like an error, so I just moved the check up to make it
simpler.  I also thing the "free space inode generation did not match"
messages
should only happen once, but are getting kicked out everytime something gets
removed, which is because the block group is not marked as cleared, so we just
need to go to free_cache so it gets marked to be cleared so we don''t
get the
same message over and over again.  Let me know how this works out for you,
thanks,

Josef

misspelling:
