This - ioctl uses struct xfs_inumbers_req to set up a bulk transfer from the - kernel: - - struct xfs_inumbers_req { - struct xfs_bulk_ireq hdr; - struct xfs_inumbers inumbers[]; - }; - - See below for the xfs_inumbers structure definition. - - struct xfs_bulk_ireq { - uint64_t ino; - uint32_t flags; - uint32_t icount; - uint32_t ocount; - uint32_t agno; - uint64_t reserved[5]; - }; - - hdr describes the information to query. The layout and behavior are - documented in the ioctl_xfs_bulkstat(2) manpage and will not be - discussed further here. - - - inumbers is an array of struct xfs_inumbers which is described below. - The array must have at least icount elements. - - struct xfs_inumbers { - uint64_t xi_startino; - uint64_t xi_allocmask; - uint8_t xi_alloccount; - uint8_t xi_version; - uint8_t xi_padding[6]; - }; - - This structure describes inode usage information for a group of 64 - consecutive inode numbers. - - xi_startino is the first inode number of this group. - - xi_allocmask is a bitmask telling which inodes in this group are - allocated.
