Linux kernel source tree
cefd809251
[BUG]
Currently we only enforcing the free space tree for bs < ps cases, but
with the recently added bs > ps support, we lack the free space tree
enforcing, causing explicit v1 cache mount option to fail on bs > ps
cases:
# mount -o space_cache=v1 /dev/test/scratch1 /mnt/btrfs/
mount: /mnt/btrfs: wrong fs type, bad option, bad superblock on /dev/mapper/test-scratch1, missing codepage or helper program, or other error.
dmesg(1) may have more information after failed mount system call.
# dmesg -t | tail -n7
BTRFS: device fsid ac14a6fa-4ec9-449e-aec9-7d1777bfdc06 devid 1 transid 11 /dev/mapper/test-scratch1 (253:3) scanned by mount (2849)
BTRFS info (device dm-3): first mount of filesystem ac14a6fa-4ec9-449e-aec9-7d1777bfdc06
BTRFS info (device dm-3): using crc32c checksum algorithm
BTRFS warning (device dm-3): support for block size 8192 with page size 4096 is experimental, some features may be missing
BTRFS warning (device dm-3): space cache v1 is being deprecated and will be removed in a future release, please use -o space_cache=v2
BTRFS warning (device dm-3): v1 space cache is not supported for page size 4096 with sectorsize 8192
BTRFS error (device dm-3): open_ctree failed: -22
[FIX]
Just enable the same free space tree for bs > ps cases, aligning the
behavior to bs < ps cases.

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 reStructuredText 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.
