Tested on larger filesystems than 100T too, but let's use Fermi approximation. Next size is 1P. Removed interaction with block-level SSD caching subsystems. These are really btrfs metadata vs. a lower block layer, and have nothing to do with bees. Added mixed block groups to the tested list, as mixed block groups required explicit support in the extent scanner. Added btrfs-convert to the tested list. btrfs-convert has various problems with space allocation in general, but these can be solved by carefully ordered balances after conversion, and they have nothing to do with bees. In-kernel dedupe is dead and the stubs were removed years ago. Remove it from the list. btrfs send now plays nicely with bees on all supportable kernels, now that stable/linux-4.19.y is dead. Send workaround is only needed for kernels before v5.4 (technically v5.2, but nobody should ever mount a btrfs with kernel v5.1 to v5.3). bees will pause automatically when deduping a subvol that is currently running a send. bees will no longer gratuitously refragment data that was defragmented by autodefrag. Explicitly list all the RAID profiles tested so far, as there have been some new ones. Explicitly list other deduplicators tested. Sort the list of btrfs features alphabetically. Add scrub and balance, which have been tested with bees since the beginning. New tested btrfs features: block-group-tree, raid1c3, raid1c4. New untested btrfs features: squotas, raid-stripe-tree.
