In the Linux kernel, the following vulnerability has been resolved:
block: integrity: Do not call setpagedirty_lock()
Placing multiple protection information buffers inside the same page can lead to oopses because setpagedirty_lock() can't be called from interrupt context.
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 setpagedirtylock() and remove the last argument to biointegrityunpinbvec().
