| * libmtd - MTD library description data structure. |
| * @sysfs_mtd: MTD directory in sysfs |
| * @mtd: MTD device sysfs directory pattern |
| * @mtd_dev: MTD device major/minor numbers file pattern |
| * @mtd_name: MTD device name file pattern |
| * @mtd_type: MTD device type file pattern |
| * @mtd_eb_size: MTD device eraseblock size file pattern |
| * @mtd_size: MTD device size file pattern |
| * @mtd_min_io_size: minimum I/O unit size file pattern |
| * @mtd_subpage_size: sub-page size file pattern |
| * @mtd_oob_size: MTD device OOB size file pattern |
| * @mtd_region_cnt: count of additional erase regions file pattern |
| * @mtd_flags: MTD device flags file pattern |
| * @sysfs_supported: non-zero if sysfs is supported by MTD |
| * @offs64_ioctls: %OFFS64_IOCTLS_SUPPORTED if 64-bit %MEMERASE64, |
| * %MEMREADOOB64, %MEMWRITEOOB64 MTD device ioctls are |
| * supported, %OFFS64_IOCTLS_NOT_SUPPORTED if not, and |
| * %OFFS64_IOCTLS_UNKNOWN if it is not known yet; |
| * |
| * Note, we cannot find out whether 64-bit ioctls are supported by MTD when we |
| * are initializing the library, because this requires an MTD device node. |
| * Indeed, we have to actually call the ioctl and check for %ENOTTY to find |
| * out whether it is supported or not. |
| * |
| * Thus, we leave %offs64_ioctls uninitialized in 'libmtd_open()', and |
| * initialize it later, when corresponding libmtd function is used, and when |
| * we actually have a device node and can invoke an ioctl command on it. |
