Naohiro Aota c4d2704c9a btrfs-progs: utils: introduce queue_param helper function
Introduce the queue_param helper function to get a device request queue
parameter. This helper will be used later to query information of a zoned
device.

Furthermore, rewrite is_ssd() using the helper function.

David Sterba 922eaa7b54 btrfs-progs: build: fix linking with static libmount
The libmount dependency has been added in commit 61ecaff036
("btrfs-progs: build: add libmount dependency"), and static build got
broken. There are functions that do basically the same thing and also
share the name, which in turn fails at link time.

  ld: /../lib64/libmount.a(libcommon_la-canonicalize.o): in function `canonicalize_dm_name':
  util-linux-2.34/lib/canonicalize.c:58: multiple definition of `canonicalize_dm_name';
	  common/path-utils.static.o:btrfs-progs/common/path-utils.c:286: first defined here

In case the collision can be resolved by renaming, it's done
(canonicalize_path and parse_size). There are 2 symbols from selinux
that are substituted by a weak aliases during the static build.

There's one new warning due to use of getgrnam_r in libmount that
depends on dynamic linking and may not work properly with static build.
We're not using the related functions directly or indirectly, so it
should be safe to ignore the warnings.

  ld: ../lib64/libmount.a(la-utils.o): in function `mnt_get_gid':
  util-linux-2.34/libmount/src/utils.c:625: warning: Using 'getgrnam_r' in statically linked applications

Qu Wenruo 90020a7605 btrfs-progs: mkfs: refactor how we handle sectorsize override
There are several problems for current sectorsize check:
- No check at all for sectorsize
  This means you can even specify "-s 62k".

- No way to specify sectorsize smaller than page size

Fix all these problems by:
- Introduce btrfs_check_sectorsize()
  To do:
  * power of 2 check for sectorsize
  * lower and upper boundary check for sectorsize
  * warn about sectorsize mismatch with page size

- Remove the max() between page size and sectorsize
  This allows us to override the sectorsize for 64K page systems.

- Make nodesize calculation based on sectorsize
  No need to use page size any more.
  Users who specify sectorsize manually really know what they are doing,
  and we have warned them already.

Boris Burkov 92d92e99b7 btrfs-progs: mkfs: support free space tree as -R option
Add a runtime feature (-R) flag for the free space tree. A filesystem
that is mkfs'd with -R free-space-tree then mounted with no options has
the same contents as one mkfs'd without the option, then mounted with
'-o space_cache=v2'.

The only tricky thing is in exactly how to call the tree creation code.
Using btrfs_create_free_space_tree as is did not quite work, because an
extra reference to the eb (root->commit_root) is leaked, which mkfs
complains about with a warning. I opted to follow how the uuid tree is
created by adding it to the dirty roots list for cleanup by
commit_tree_roots in commit_transaction. As a result,
btrfs_create_free_space_tree no longer exactly matches the version in
the kernel sources.

David Sterba f1507716c6 btrfs-progs: mkfs: switch to single as default profile for multiple-devices
The single profile is better suited as default for data on multiple
devices. Switch from RAID0 because:

- it's easier to convert to other profiles, as single consumes some
  chunks per device, but RAID0 has chunks on all devices regardless of
  the used space

- RAID0 has no redundancy and compared one disk failure affects many
  files due to striping, while with single the chances are a bit higher
  that complete files are stored on one device

- when the device sizes are not equal and not even close to equal, the
  maximum achievable size with RAID0 is size of the smallest device due
  to striping, with single it's the sum of all device sizes

The changed defaults could affect scripts and deployments that rely on
the old values, but given the number of possible profiles for multiple
devices let's hope that they're specified explicitly in majority of
cases.

Filipe Manana df090f6eb7 Btrfs-progs: mkfs, fix metadata corruption when using mixed mode
When creating a filesystem with mixed block groups, we are creating two
space info objects to track used/reserved/pinned space, one only for data
and another one only for metadata.

This is making fstests test case generic/416 fail, with btrfs' check
reporting over an hundred errors about bad extents:

  (...)
  bad extent [17186816, 17190912), type mismatch with chunk
  bad extent [17195008, 17199104), type mismatch with chunk
  bad extent [17203200, 17207296), type mismatch with chunk
  (...)

Because, surprisingly, this results in block groups that do not have the
BTRFS_BLOCK_GROUP_DATA flag set but have data extents allocated in them.
This is a regression introduced in btrfs-progs v5.2.

So fix this by making sure we only create one space info object, for both
metadata and data, when mixed block groups are enabled.
