Our file system has a translation capability for S3-to-posix. The current value of 1kiB is enough to cover S3 keys, but does not allow encoding of %xx escape characters. The limit is increased to (PATH_MAX - 1), as we need 3 x 1024 and that is close to PATH_MAX (4kB) already. -1 is used as the terminating null is not included in the length calculation. Testing large file names was hard with libfuse/example file systems, so I created a new memfs that does not have a 255 file name length limitation. https://github.com/libfuse/libfuse/pull/1077 The connection is initialized with FUSE_NAME_LOW_MAX, which is set to the previous value of FUSE_NAME_MAX of 1024. With FUSE_MIN_READ_BUFFER of 8192 that is enough for two file names + fuse headers. When FUSE_INIT reply sets max_pages to a value > 1 we know that fuse daemon supports request buffers of at least 2 pages (+ header) and can therefore hold 2 x PATH_MAX file names - operations like rename or link that need two file names are no issue then.

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.
