The double free oops part of this bug was my fault and fixed as part of
a log recovery reorganization:

xfs: fix double free in xlog_recover_commit_trans
When an error occurs during buffer submission in
xlog_recover_commit_trans(), we free the trans structure twice. Fix
it by only freeing the structure in the caller regardless of the
success or failure of the function.
The original corrupted metadata is probably caused by your RAID.
