Please describe the problem.

when unlocking multiple files, files are not hard linked, but they are if unlocked individually

What steps will reproduce the problem?

I don't really know. Currently I have a repository that exhibits the problem:

%git status --> all clean

# this works as expected
%git annex unlock bucket/tata
%ls -li bucket/tata
33292697 -rw-rw-r-- 2 karl qbstaff 102400000 Dec  7 19:02 bucket/tata
%find . -inum 33292697
git annex lock bucket/tata

This does not:

%git annex unlock bucket/
%ls -li bucket/tata 
33292708 -rw-rw-r-- 1 karl qbstaff 102400000 Dec  7 19:02 bucket/tata
%find . -inum 33292708

As you can see, now the inode is wrong (different from the annex object file), and the unlocked file is not a hard link. The only difference is the argument to git annex unlock This is really annoying, I switched to V6 for this particular feature, I have a large repository to update and it takes ages since files are copied instead of hard linked.

Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

Yes, we use it on a daily basis and love it. Note that we will have to switch to LFS for a lot of use cases because gitlab no longer supports git annex from v9 release.
