The option "--clear-ino-cache" is not really that suitable for "btrfs
check" group.
Let's move it to "btrfs rescue" group to fix those small hiccups, just
like the existing "btrfs rescue fix-device-size" command.
For now, "btrfs check --clear-ino-cache" would still work, with one
extra warning referring to "btrfs rescue clear-ino-cache".
This is mostly to reduce the surprise, and keep script users (I doubt if
there is any though) happy for now.
In the next or two releases, we would fully remove the support in "btrfs
check" group.
Another small change is, in the documents, we refer to the feature as
"inode map", which doesn't match with the mount option documents.
Since we're here, unify them to "inode cache" feature.
