Module inode 

Inode and path resolution: mapping between inodes, logical addresses, and paths

Covers looking up the subvolume root ID that contains a given file, resolving an inode number to its filesystem paths, mapping a logical byte address back to the inodes that reference it, and resolving a subvolume ID to its path within the filesystem.

Structs

InoLookupUserResult

Result of an unprivileged inode lookup (BTRFS_IOC_INO_LOOKUP_USER).

LogicalInoResult

Result from logical-ino resolution: (inode, offset, root)

Functions

ino_lookup_user

Unprivileged inode lookup: resolve a subvolume’s name and parent path.

ino_paths

Get file system paths for the given inode.

logical_ino

Get inode, offset, and root information for a logical address.

lookup_path_rootid

Look up the tree ID (root ID) of the subvolume containing the given file or directory.

subvolid_resolve

Resolve a subvolume ID to its full path on the filesystem.
