The main purpose is to have it run by developers changing something around btrfs send / receive and probably the backref walker (while there exists a separate test not requiring fssum for backrefs). I think we can get them to install fssum. > Could the same test be done w/o fssum, or should we maybe put a copy > of fssum into xfstests/src/fssum.c ? I don't know any adequate replacement for fssum in this case. The purpose is to build a checksum for a whole file system tree, including data and partly metadata. I don't feel like copying fssum from far-progs into xfstests, though it probably won't hurt much. However, I cannot promise we won't make changes to it for far-progs, probably creating two incompatible versions of fssum in the wild. Arne? > Or does fssum exist in any standard distro package? It doesn't. Perhaps Josef can hurry and make a Fedora package for it, if that prevents a separate copy to xfstests :-) Thanks, -Jan > Thanks, > -Eric > >> --- >> README | 3 + >> common/config | 2 + >> tests/btrfs/314 | 113 >> +++++++++++++++++++++++++++++++++++++++++++++++++++ >> tests/btrfs/314.out | 4 ++ >> tests/btrfs/group | 1 + >> 5 files changed, 123 insertions(+), 0 deletions(-) >> create mode 100755 tests/btrfs/314 >> create mode 100644 tests/btrfs/314.out >> >> diff --git a/README b/README >> index d4d4f31..56b31f0 100644 >> --- a/README >> +++ b/README >> @@ -26,6 +26,9 @@ Preparing system for tests (IRIX and Linux): >> http://www.extra.research.philips.com/udf/, then copy the udf_test >> binary to xfstests/src/.
