Official description

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

block: integrity: Do not call set_page_dirty_lock()

Since a protection information buffer is not backed by a file there is no point in setting its page dirty, there is nothing to synchronize. Drop the call to set_page_dirty_lock() and remove the last argument to bio_integrity_unpin_bvec().
