I didn't realize this last night, but we allocate sbi->s_flex_counts so it is big enough in case the filesystem gets resized to the maximum size. So that's why it was trying to allocate that many flex groups. On the other hand, it means that it's much more likely for us to need the extra memory. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
