This series is based on linux-next + these 2 small patches applies on top: https://lore.kernel.org/lkml/20220526034609.480766-1-sarava...@google.com/
A lot of the deferred_probe_timeout logic is redundant with fw_devlink=on. Also, enabling deferred_probe_timeout by default breaks a few cases. This series tries to delete the redundant logic, simplify the frameworks that use driver_deferred_probe_check_state(), enable deferred_probe_timeout=10 by default, and fixes the nfsroot failure case. Patches 1 to 3 are fairly straightforward and can probably be applied right away. Patches 4 to 9 are related and are the complicated bits of this series. Patch 8 is where someone with more knowledge of the IP auto config code can help rewrite the patch to limit the scope of the workaround by running the work around only if IP auto config fails the first time around. But it's also something that can be optimized in the future because it's already limited to the case where IP auto config is enabled using the kernel commandline. Yoshihiro/Geert, If you can test this patch series and confirm that the NFS root case works, I'd really appreciate that.
