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 we can reflink and dedupe blocks within the same file...
|
|
# - Create a file with three distinct blocks ABB
|
|
# - Reflink block zero to the multiple-of-three blocks
|
|
# - Reflink block one to the multiple-of-five blocks
|
|
# - Dedupe block two to the multiple-of-seven blocks
|
|
# - Check that we successfully avoid deduping with holes, unwritten
|
|
# extents, and non-matches; but actually dedupe real matches.
