[Qemu-devel] [RFC PATCH for 2.10 3/3] docker: ignore submodules when checking diff
Posted by Alex Bennée 8 years, 6 months ago
The QEMU tree often has dirty submodules in it but this will confuse
things as git stash is not going to save their state directly. They
are likely just dirty from build files anyway. Ignore them in the
diff-index command.

It's annoying that our build dirties a submodule in the first place; it
would be nice to get rid of those bugs in our build process (ideally,
the build should treat submodule directories as read-only).  But that is
a bigger effort, so I'm okay with your hack in the meantime.
