Building fs/jfs with clang and '-fms-extensions' errors with:
In file included from fs/jfs/jfs_unicode.c:8:
fs/jfs/jfs_incore.h:86:13: error: type name does not allow function specifier to be specified
86 | unchar _inline[128];
| ^
fs/jfs/jfs_incore.h:86:20: error: expected member name or ';' after declaration specifiers
86 | unchar _inline[128];
| ~~~~~~~~~~~~~~^
'-fms-extensions' in clang enables several other Microsoft specific
keywords such as _inline [1], presumably for compatibility with MSVC, as
Microsoft's documentation [2] mentions:
For compatibility with previous versions, _inline and _forceinline are
synonyms for __inline and __forceinline, respectively
Rename the _inline array in 'struct jfs_inode_info' to _inline_sym to
avoid this conflict, which is not a large workaround as this member is
only ever referred to via the i_inline macro.

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.
