Those busy inodes are pretty common in current kernels, I don't know if that's related -- I doubt it since it is for different bdevs. Do you have any clue what to test, how to debug that? @Honza: this is the one we talked about earlier, you wanted to see details, but I thought it disappeared. (Just in case you are interested.) Thanks.
