[PATCH 0/3] btrfs-progs: updates related to seed device and v6.17 kernel

[Qu Wenruo <wqu@suse.com>]

Kernel commit 40426dd147ff ("btrfs: use the super_block as holder when
mounting file systems") changed the block device holder so that each
device of a mounted btrfs can only belong to a single fs.

This is fine for most users, but for a corner case of seed devices, it
can be problematic.

As previously we allow the same seed device to be mounted through both
the seed device and the sprouted fs, as at that time all btrfs devices
share the same holder.

But now since each block device can only belong to a single mounted fs,
it means the seed device can only be mounted through either the seed
device itself or a sprouted fs, not both at the same time.

This series will update the docs to be more explicit about the seed
device mounting behavior, and updated the test case misc/046 to follow
the new kernel behavior.

And since we're here, also update a note where newer kernel fix a bug in
orphan roots cleanup.
