In current code, swiotlb_bounce() may do partial sync's correctly in some circumstances, but may incorrectly fail in other circumstances. The failure cases require both of these to be true: 1) swiotlb_align_offset() returns a non-zero "offset" value 2) the tlb_addr of the partial sync area points into the first "offset" bytes of the _second_ or subsequent swiotlb slot allocated for the mapping Code added in commit |

README
Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the reStructuredText markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
