The global sequence counter is an - * unsigned 64-bit integer and we assume it never overflows. The @sqnum - * (sequence number) is used to distinguish between older and newer versions of - * logical eraseblocks. - * - * There are 2 situations when there may be more then one physical eraseblock - * corresponding to the same logical eraseblock, i.e., having the same @vol_id - * and @lnum values in the volume identifier header.

Because UBI may erase physical eraseblocks asynchronously, the following - * situation is possible: L is asynchronously erased, so P is scheduled for - * erasure, then L is written to,i.e. mapped to another physical eraseblock P1, - * so P1 is written to, then an unclean reboot happens. Result - there are 2 - * physical eraseblocks P and P1 corresponding to the same logical eraseblock - * L. But P1 has greater sequence number, so UBI picks P1 when it attaches the - * flash. - * - * 2. From time to time UBI moves logical eraseblocks to other physical - * eraseblocks for wear-leveling reasons. If, for example, UBI moves L from P - * to P1, and an unclean reboot happens before P is physically erased, there - * are two physical eraseblocks P and P1 corresponding to L and UBI has to - * select one of them when the flash is attached. The @sqnum field says which - * PEB is the original (obviously P will have lower @sqnum) and the copy. But - * it is not enough to select the physical eraseblock with the higher sequence - * number, because the unclean reboot could have happen in the middle of the - * copying process, so the data in P is corrupted. It is also not enough to - * just select the physical eraseblock with lower sequence number, because the - * data there may be old (consider a case if more data was added to P1 after - * the copying). Moreover, the unclean reboot may happen when the erasure of P - * was just started, so it result in unstable P, which is "mostly" OK, but - * still has unstable bits. - * - * UBI uses the @copy_flag field to indicate that this logical eraseblock is a - * copy. UBI also calculates data CRC when the data is moved and stores it at - * the @data_crc field of the copy (P1). So when UBI needs to pick one physical - * eraseblock of two (P or P1), the @copy_flag of the newer one (P1) is - * examined. If it is cleared, the situation* is simple and the newer one is - * picked. If it is set, the data CRC of the copy (P1) is examined. If the CRC - * checksum is correct, this physical eraseblock is selected (P1). Otherwise - * the older one (P) is selected. - * - * Note, there is an obsolete @leb_ver field which was used instead of @sqnum - * in the past. But it is not used anymore and we keep it in order to be able - * to deal with old UBI images. It will be removed at some point. - * - * There are 2 sorts of volumes in UBI: user volumes and internal volumes. - * Internal volumes are not seen from outside and are used for various internal - * UBI purposes. In this implementation there is only one internal volume - the - * layout volume. Internal volumes are the main mechanism of UBI extensions. - * For example, in future one may introduce a journal internal volume. Internal - * volumes have their own reserved range of IDs. - * - * The @compat field is only used for internal volumes and contains the "degree - * of their compatibility". It is always zero for user volumes. This field - * provides a mechanism to introduce UBI extensions and to be still compatible - * with older UBI binaries. For example, if someone introduced a journal in - * future, he would probably use %UBI_COMPAT_DELETE compatibility for the - * journal volume. And in this case, older UBI binaries, which know nothing - * about the journal volume, would just delete this volume and work perfectly - * fine. This is similar to what Ext2fs does when it is fed by an Ext3fs image - * - it just ignores the Ext3fs journal. - * - * The @data_crc field contains the CRC checksum of the contents of the logical - * eraseblock if this is a static volume. In case of dynamic volumes, it does - * not contain the CRC checksum as a rule. The only exception is when the - * data of the physical eraseblock was moved by the wear-leveling unit, then - * the wear-leveling unit calculates the data CRC and stores it in the - * @data_crc field. And of course, the @copy_flag is %in this case. - * - * The @data_size field is used only for static volumes because UBI has to know - * how many bytes of data are stored in this eraseblock. For dynamic volumes, - * this field usually contains zero. The only exception is when the data of the - * physical eraseblock was moved to another physical eraseblock for - * wear-leveling reasons. In this case, UBI calculates CRC checksum of the - * contents and uses both @data_crc and @data_size fields. In this case, the - * @data_size field contains data size. - * - * The @used_ebs field is used only for static volumes and indicates how many - * eraseblocks the data of the volume takes. For dynamic volumes this field is - * not used and always contains zero. - * - * The @data_pad is calculated when volumes are created using the alignment - * parameter. So, effectively, the @data_pad field reduces the size of logical - * eraseblocks of this volume.
