This makes it clear when we are using "mount ; umount" versus "mount
-o remount" for most file systems. The reason for this distinction is
(a) tests may want to test the difference between what happens on the
remount versus the munt paths, (b) with tmpfs, "mount ; umount" will
cause the contents of all of the files to disappear which makes many
tests sad, and (c) some mount options may not be changed using "mount
-o remount".
Currently _test_mount performs "_test_mount ; _test_umount"
so mechnically rename this function to _test_cycle_mount. This was
done mechnically using the script fragment:
git grep -E "_test_remount" | \
awk -F: '{print $1}' | sort -u | grep -v tests/xfs/189 \
xargs sed -i 's/_test_remount/_test_cycle_mount/g'

# Ensure that truncating the last block in a reflinked file CoWs appropriately:
|
|
# - Create a file that doesn't end on a block boundary
|
|
# - Create two reflink clones of the file
|
|
# - Shorten one of the clones with truncate
|
|
# - Lengthen the other clone with truncate
|
|
# - Check that the reflinked areas are still there.
