Jan Kara 16c5468859 ext4: Allow parallel DIO reads ... We can easily support parallel direct IO reads. We only have to make sure we cannot expose uninitialized data by reading allocated block to which data was not written yet, or which was already truncated. That is easily achieved by holding inode_lock in shared mode - that excludes all writes, truncates, hole punches. We also have to guard against page writeback allocating blocks for delay-allocated pages - that race is handled by the fact that we writeback all the pages in the affected range and the lock protects us from new pages being created there.
