Return to 165 CVS log

Up to [Development] / xfs-cmds / xfstests

Use configured XFS_IO_PROG binary

We should use XFS_IO_PROG variable rather than calling xfs_io
directly and relying on teh path to pick up the correct binary
for the test.
Merge of master-melb:xfs-cmds:30993a by kenmcd.

  Use XFS_IO_PROG, not xfs_io.

# FS QA Test No. 165

# Test out prealloc, direct writes and buffered read
# Some experimentation when looking at 
#   pv#962014 - DMF 3.7 reading incorrect data 
# Doesn't actually reproduce the problem but it tried to :-)
