Qu Wenruo 0a99cd08e2 btrfs: properly reject clear_cache and v1 cache for block-group-tree
commit 64b5d5b2852661284ccbb038c697562cc56231bf upstream.

[BUG]
With block-group-tree feature enabled, mounting it with clear_cache
would cause the following transaction abort at mount or remount:

  BTRFS info (device dm-4): force clearing of disk cache
  BTRFS info (device dm-4): using free space tree
  BTRFS info (device dm-4): auto enabling async discard
  BTRFS info (device dm-4): clearing free space tree
  BTRFS info (device dm-4): clearing compat-ro feature flag for FREE_SPACE_TREE (0x1)
  BTRFS info (device dm-4): clearing compat-ro feature flag for FREE_SPACE_TREE_VALID (0x2)
  BTRFS error (device dm-4): block-group-tree feature requires fres-space-tree and no-holes
  BTRFS error (device dm-4): super block corruption detected before writing it to disk
  BTRFS: error (device dm-4) in write_all_supers:4288: errno=-117 Filesystem corrupted (unexpected superblock corruption detected)
  BTRFS warning (device dm-4: state E): Skipping commit of aborted transaction.

[CAUSE]
For block-group-tree feature, we have an artificial dependency on
free-space-tree.

This means if we detect block-group-tree without v2 cache, we consider
it a corruption and cause the problem.

For clear_cache mount option, it would temporary disable v2 cache, then
re-enable it.

But unfortunately for that temporary v2 cache disabled status, we refuse
to write a superblock with bg tree only flag, thus leads to the above
transaction abortion.

[FIX]
For now, just reject clear_cache and v1 cache mount option for block
group tree.  So now we got a graceful rejection other than a transaction
abort:

  BTRFS info (device dm-4): force clearing of disk cache
  BTRFS error (device dm-4): cannot disable free space tree with block-group-tree feature
  BTRFS error (device dm-4): open_ctree failed

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
