libfuse 3.6.0

• Added a new example (passthrough_hp). The functionality is similar to passthrough_ll, but the implementation focuses on performance and correctness rather than simplicity.
• Added support for fuse kernel feature max_pages which allows to increase the maximum number of pages that can be used per request. This feature was introduced in kernel 4.20. max_pages is set based on the value in max_write. By default max_write will be 1MiB now for kernels that support max_pages. If you want smaller buffers or writes you have to set max_write manually.
