pub fn chunk_list(fd: BorrowedFd<'_>) -> Result<Vec<ChunkEntry>>Expand description
Walk the chunk tree and return one ChunkEntry per stripe, including
bytes-used from the extent tree.
The returned list is in chunk-tree order (ascending logical offset); call
sites are responsible for any further sorting. For each logical chunk the
used field is populated by a single extent-tree lookup; if that lookup
fails the field is set to 0 rather than propagating an error.
Requires CAP_SYS_ADMIN.
