6.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jens Axboe <axboe@xxxxxxxxx>
commit 11893e144ed75be55d99349760513ca104781fc0 upstream.
If the iovec inside the kmsg isn't already allocated AND one gets
expanded beyond the fixed size, then the request may not already have
been marked for cleanup. Ensure that it is.
