Struct RescueClearInoCacheCommand 

pub struct RescueClearInoCacheCommand { /* private fields */ }

Remove leftover items pertaining to the deprecated inode cache feature

For every fs tree (the default subvolume and every user subvolume), walks the items keyed under BTRFS_FREE_INO_OBJECTID (and historically also BTRFS_FREE_SPACE_OBJECTID, which old kernels used for the per-inode cache bitmap), drops every referenced data extent via the delayed-ref queue, and deletes the items themselves. The transaction crate’s data-ref drop path also trims the csum tree for any fully-freed extent.

The device must not be mounted.
