Comment 1 R.Nageswara Sastry 2014-06-25 11:27:00 UTC
Upon request mangled file system image for 'fsfuzzer' will be provided.
Comment 2 Eric Sandeen 2016-09-22 16:24:39 UTC
I'm batch-closing all xfs bugs which are more than 1 year old, sorry about that.

If you still have this issue on a current kernel, please retest and re-open with this information.

Thanks,
-Eric
