Win7 is creating UDF filesystems with single partition with number 8192. Current partition descriptor scanning code does not handle this well as it incorrectly assumes that partition numbers will form mostly contiguous space of small numbers. This results in unmountable media due to errors like: UDF-fs: error (device dm-1): udf_read_tagged: tag version 0x0000 != 0x0002 || 0x0003, block 0 UDF-fs: warning (device dm-1): udf_fill_super: No fileset found Fix the problem by handling partition descriptors in a way that sparse partition numbering does not matter.

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 Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
