Not all inode attributes are supported by all filesystems, but for the basic stats (which are returned by stat(2) and friends) all of them will have some value, even if that doesn't reflect a real attribute of the file. Btime is different, in that filesystems are free to report or not report a value in statx. If the value is available, then STATX_BTIME bit is set in stx_mask. When caching the value of btime, remember the availability of the attribute as well as the value (if available). This is done by using the FUSE_I_BTIME bit in fuse_inode->state to indicate availability, while using fuse_inode->inval_mask & STATX_BTIME to indicate the state of the cache itself (i.e. set if cache is invalid, and cleared if cache is valid).

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.
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.
