Peter Zijlstra 97a894136f mm: Remove i_mmap_lock lockbreak ... Hugh says: "The only significant loser, I think, would be page reclaim (when concurrent with truncation): could spin for a long time waiting for the i_mmap_mutex it expects would soon be dropped? " Counter points: - cpu contention makes the spin stop (need_resched()) - zap pages should be freeing pages at a higher rate than reclaim ever can I think the simplification of the truncate code is definitely worth it. Effectively reverts: 2aa15890f3 ("mm: prevent concurrent unmap_mapping_range() on the same inode") and takes out the code that caused its problem.
