This third test depends on test files created in second test, and I
guess this could confuse people at debug time if any of the tests
failed.
So how about remove all the files and call "open_by_handle -c ..."
before each test? e.g. (I use testdir and don't remove lost+found dir
because extN needs it for fsck)
testdir=$SCRATCH_MNT/testdir
mkdir -p $testdir
# Check stale handles to deleted files
src/open_by_handle -c $testdir $numfiles
src/open_by_handle -d $testdir $numfiles
# Check non-stale handles to linked files
rm -f $testdir/*
...
# Check non-stale handles to files that were hardlinked and original
# deleted
rm -f $testdir/*
src/open_by_handle -c $testdir $numfiles
... -l ..
... -u ..
Thanks,
