CVE-2024-35787

In the Linux kernel, the following vulnerability has been resolved:

md/md-bitmap: fix incorrect usage for sb_index

Commit d7038f951828 ("md-bitmap: don't use ->index for pages backing the
bitmap file") removed page->index from bitmap code, but left wrong code
logic for clustered-md. current code never set slot offset for cluster
nodes, will sometimes cause crash in clustered env.
