| # FS QA Test No. 164 |
| # |
| # To test for short dio reads on IRIX and Linux - pv#962005/962547 |
| # http://bugworks.engr.sgi.com/query.cgi/962005 |
| # |
| # In particular we are interested in dio_reads for the cases of: |
| # * eof on a hole |
| # * eof on an unwritten extent |
| # * eof on a sector boundary and not on a sector boundary |
