Qu Wenruo 3875c14a5a btrfs-progs: image: fix restored image size misalignment ... [BUG] There is a small device size misalignment between the super block device size and the device extent size: total_bytes 10737418240 <<< bytes_used 15097856 dev_item.total_bytes 10737418240 dev_item.bytes_used 1094713344 item 0 key (DEV_ITEMS DEV_ITEM 1) itemoff 16185 itemsize 98 devid 1 total_bytes 1095761920 bytes_used 1094713344 ^^^^^^^^^^ [CAUSE] In fixup_device_size(), we only reset superblock device item size, which will be overwritten in write_dev_supers() using btrfs_device::total_bytes. And it doesn't touch btrfs_superblock::total_bytes either. [FIX] So fix the small mismatch by also resetting btrfs_device::total_bytes, btrfs_device::bytes_used and btrfs_superblock::total_bytes. Thankfully since commit 73dd4e3c87 ("btrfs-progs: image: Don't modify the chunk and device tree if the source dump is single device") single device dump won't have such problem, but it's still worth for multi-device dump.
