Set the bi_skip_dm_default_key flag on bios that are targeting the
contents of an encrypted file and therefore should not be en/decrypted
by dm-default-key.

Add a flag bi_skip_dm_default_key to struct bio. This flag indicates
that dm-default-key should not en/decrypt the bio, due to it targeting
the contents of an encrypted file.
When a bio is cloned, copy the bi_skip_dm_default_key flag.

Add a new device-mapper target "dm-default-key" that is similar to
dm-crypt but has two main differences:
- It uses the blk-crypto API instead of the regular crypto API. This
allows it to take advantage of inline encryption hardware such as that
commonly built into UFS ho
This series adds "metadata encryption" support to ext4 and f2fs via a
new device-mapper target dm-default-key. dm-default-key encrypts all
data on a block device that isn't already encrypted by the filesystem.
Except for the passthrough support, dm-default-key is basically the same
as the propose
From: Eric Biggers
bio_crypt_set_ctx(), blk_crypto_init_key(), and
blk_crypto_start_using_key() are needed to use inline encryption; see
Documentation/block/inline-encryption.rst. Export them so that
dm-default-key can use them. The only reason these weren't exported
before was that inline encr
Hand over immutable flag clearing functionality from setflags to
clearflags, since the flag name is immutable rather than noimmutable.
And support setting functionality in subcommand setflags.

This patch introduces a new helper log_type_to_seg_type() to convert
log type to segment data type, and uses it to clean up opened codes
in build_curseg(), and also it fixes to convert log type before use
in do_write_page().

If checkpoint is off, let's set segment as free once all newly
written datas were removed, it fixes below case:
dd if=/dev/zero of=f2fs.img bs=1M count=64
mkfs.f2fs -f f2fs.img
mount -o checkpoint=disable:10% f2fs.img mnt
dd if=/dev/zero of=mnt/file bs=1M count=19
sync
rm mnt/file
dd if=/dev/zero
