Analyze and fix the following issue in the Linux kernel code: UBI: fix forward compatibility
Problem Details: Commit 0798cea8c2e1afee59686c51d27d0e96b05e42d1 "UBI: improve corrupted flash handling" broke delet-compatible volumes handling - it introduced a limit of 8 eraseblocks which may be corrupted. And delete-compatible eraseblocks are added to the "corrupted" list, so if we'd have a large delete-compatible...
