Strange. I did remove a cond_resched() from invalidate_mapping_pages() so
that it could be run under spinlock but I cannot believe that you had so
many pages cached that the invalidate took more than ten seconds.
Does the machine recover and otherwise work OK?
Does it appear to you that the mount _really_ took over ten seconds system
CPU time??
