Dear BTRFS developers,
we would like to extend our FS storage by adding two more harddisks.
At present, BTRFS is using two partitions and running in RAID1 mode. I
would like to add two more harddisks (without partitioning them) as an
additional RAID1 pair to extend the storage. In other words, we

We had an edge case issue where the requested range was just
following an existing extent. Instead of skipping to the next
extent, we used the previous one which lead to having zero
sized extents.

This patch overrides a previous one posted, as it had the logic reverted and
wrong.
The lookup_first_ordered_extent() was done on the wrong inode, and the
->delalloc_bytes test was wrong, as the following btrfs_wait_ordered_range()
would only invoke a range write and wouldn't write the entire file
In order to save free space cache, we need an inode to hold the data, and we
need a special item to point at the right inode for the right block group. So
first, create a special item that will point to the right inode, and the number
of extent entries we will have and the number of bitmaps we wil
If something goes wrong with the free space cache we need a way to make sure
it's not loaded on mount and that it's cleared for everybody. When you pass the
clear_cache option it will make it so all block groups are setup to be cleared,
which keeps them from being loaded and then they will be trun
