It sets up the remapping for the overwrite_bio but then drops it immediately without submission, causing write operations to hang.</p> <p>Fix by adding a new invalidate_committed() continuation that submits the remapped writes to the cache origin after metadata commit completes, while using the overwrite_endio hook to ensure proper completion sequencing. This maintains existing coherency. Also improve error handling in invalidate_complete() to preserve the original error status instead of using bio_io_error() unconditionally.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>dm cache: fix write hang in passthrough mode</p> <p>The invalidate_remove() function has incomplete logic for handling write hit bios after cache invalidation.
