Hey Dave,

Looks like there are some additional test failures due to this patchset.  Here
some output from a bisect I did yesterday, running only the tests which failed
on the machine where I noticed this.

# git describe
v3.4-rc2-54-g1307bbd

from patches/series:
# normal: (there's my baseline on this machine.  I noticed a larger number of 
test failures on another test box and brought that series over here)
#Failures: 030 178 230 231 232 233 250 274
#Failed 8 of 198 tests

Looks like there is a problem in
xfs-struct-xfs_buf_log_format-isn-t-variable-sized.patch,
and/or
xfs-support-discontiguous-buffers-in-the.patch.
