Btrfs relies on mapping_set_folio_order_range() to set the minimal
folio order for all its data inodes, but that function will be no-op if
transparent hugepage is not enabled.
Guard the bs > ps support behind CONFIG_TRANSPARENT_HUGEPAGE, just like
all other filesystems.

Btrfs is a general purpose copy-on-write filesystem with extents,
|
|
writable snapshotting, support for multiple devices and many more
|
|
features focused on fault tolerance, repair and easy administration.
|
|
|
|
The filesystem disk format is no longer unstable, and it's not
|
|
expected to change unless there are strong reasons to do so. If there
|
|
is a format change, file systems with a unchanged format will
|
|
continue to be mountable and usable by newer kernels.
|
|
|
|
For more information, please see the web pages at
|
|
https://btrfs.readthedocs.io
|
|
|
|
To compile this file system support as a module, choose M here. The
|
|
module will be called btrfs.

Enable run-time debugging support for the btrfs filesystem.

Additional potentially expensive checks, debugging functionality or

sysfs exported information is enabled, like leak checks of internal

- RAID mirror read policy - additional read policies for balancing

reading from redundant block group
|

profiles (currently: pid, round-robin,
|

fixed devid)
|
|
|
|
- send stream protocol v3 - fs-verity support

support RAID1* profiles on zoned devices,
|
|
RAID56 not yet supported
