Rework most of inline-encryption.rst to be easier to follow, to correct some information, to add some important details and remove some unimportant details, and to take into account the renaming from blk_keyslot_manager to blk_crypto_profile.

Currently the fscrypt inline encryption support is documented in the "Implementation details" section, and it doesn't go into much detail. It's really more than just an "implementation detail" though, as there is a user-facing mount option. Also, hardware-wrapped key support (an upcoming feature) will depend on inline encryption and will affect the on-disk format; by definition that's not just an implementation detail. Therefore, move this documentation into its own section and expand it. Link: https://lore.kernel.org/r/20210916174928.65529-4-ebiggers@kernel.org Signed-off-by: Eric Biggers <ebiggers@google.com>
When discard_max_hw_bytes was introduced, in commit 0034af036554
("block: make /sys/block/<dev>/queue/discard_max_bytes writeable"),
the discard_max_bytes documentation section was renamed to
discard_max_hw_bytes, but the references it contains to
discard_max_bytes weren't updated.
This patch refers to discard_max_hw_bytes instead. It also reflows the
paragraph so that sentences end lines.
