Is the 30 seconds to wait for a transaction commit? If it is then I'd rather mount the fs with -o commit=3 (or some other low value) and then "sleep 3" to make the test run much faster. A comment explaining why the sleep is there, what is its purpose, should also be in place. > +echo "Diffing $dir and $dir2" > +diff $dir $dir2 > + > +echo "Rewriting $dir2 partly" > +# rewrite half of each file in the snapshot > +for j in `seq 0 50`; do > + for i in `seq 10 -1 1`; do > + $XFS_IO_PROG -f -d -c "pwrite $(($i * 4096)) 4096" \ > + $dir2/foo-$j >> $seqres.full | _filter_xfs_io > + done > +done > + > +echo "Diffing $dir and $dir2" > +diff $dir $dir2 > + > +echo "Dropping key and diffing" > +_rm_enckey $SCRATCH_MNT $TEST_KEY_IDENTIFIER > +diff $dir $dir2 |& _filter_scratch | _filter_nokey_filenames > + > +$BTRFS_UTIL_PROG subvolume delete $dir > /dev/null 2>&1 What's the purpose of this subvolume delete? It's ignoring stdout and stderr, so it doesn't care whether it succeeds or fails, and we don't do any tests/checks after it.
