When running a practical stress-test on 2.6.29-rc2 trying to reproduce
an older (extent refcounting) issue, I am consistently able to hit an
oops [] and an assertion failure [].
Sorry about that, please apply the patch I just sent this morning
[PATCH] Btrfs: deal with the case that we run out of space in the cache
Superb work - the btrfs_write_out_cache oops is addressed, so now we
(separately) hit a few other assertions at: volumes.c:2013 [1],
volumes.c:2063 [2] and volumes.c:2703 [3] with the previous
reproducer.
Let me know if adding any debugging or other testing may be useful.
Thanks,
Daniel
