fatal: cannot rebase with locally recorded submodule modifications

Hello

I don't understand why git pull --rebase --recurse-submodules fails after a git reset --hard to the previous commit. I didn't touch the submodule, it's supposed to be clean:

$ git clone --recursive git@github.com:open-mpi/ompi.git [...] $ git reset --hard HEAD^ HEAD is now at 395e2c9d8f Merge pull request #7364 from awlauria/fix_compile $ git pull --rebase --recurse-submodules Fetching submodule opal/mca/hwloc/hwloc2/hwloc fatal: cannot rebase with locally recorded submodule modifications

Why is failing here?

$ git submodule status
 38433c0f5fae0b761bd20e7b928c77f3ff2e76dc opal/mca/hwloc/hwloc2/hwloc (hwloc-2.1.0rc2-33-g38433c0f)
(that's expected)

$ git status HEAD detached at 38433c0f nothing to commit, working tree clean

Thanks

Brice
