# Tests file clone functionality of btrfs ("reflinks") on directory trees.
#   - Create directory and subdirectory, each having one file
#   - Create 2 recursive reflinked copies of the tree
#   - Modify the original files
#   - Modify one of the copies

[sandeen: mostly cosmetic changes]

This and the other reflink tests should all be:

From: Koen De Wit <koen.de.wit@oracle.com>

to maintain original authorship, sorry I forgot to add that on the patches
in the middle.  Rich, if you can fix that up on commit it'd be
great, unless I need to submit V2s then I can do it.

Koen, I haven't gone over all of them, will try to get the rest
tidied up and resubmitted unless you want to - which would be
just fine!
