Subject: reflink: more tests
X-Git-Tag: v2022.05.01~2699
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=1b3dc467e458cc219828a6db030e782b30a92b89;p=xfstests-dev.git

reflink: more tests

Add more tests for unaligned copy-on-write things, and explicitly
test the ability to pass "len == 0" to mean reflink/dedupe all
the way to the end of the file".
