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.
