IsSizeTAligned could is the kernel's IS_ALIGNED #define IsQuadAligned(n) (!((size_t)(n) & 7u)) #define QuadAlign(n) (((n) + 7u) & (~7u)) #define IsQuadAligned(n) (!((size_t)(n) & 7u)) #define Quad2Align(n) (((n) + 15u) & (~15u)) #define IsQuad2Aligned(n) (!((size_t)(n) & 15u)) Though all of these could also use two macros with the same form. Something like: #define NTFS3_ALIGN(n, at) (((n) + ((at) - 1)) & (~((at) - 1))) #define NTFS3_IS_ALIGNED(n, at) (!((size_t)(n) & ((at) - 1))) So all of these could be ordered by size and use actual size #define WordAlign(n) NTFS3_ALIGN(n, 2) #define IsWordAligned(n) NTFS3_IS_ALIGNED(n, 2) #define DwordAlign(n) NTFS3_ALIGN(n, 4) #define IsDwordAligned(n) NTFS3_IS_ALIGNED(n, 4) #define QuadAlign(n) NTFS3_ALIGN(n, 8) #define IsQuadAligned(n) NTFS3_IS_ALIGNED(n, 8) #define Quad2Align(n) NTFS3_ALIGN(n, 16) #define IsQuad2Aligned(n) NTFS3_IS_ALIGNED(n, 16) #define IsSizeTAligned(n) NTFS3_IS_ALIGNED(n, sizeof(size_t)) > +#ifdef CONFIG_PRINTK > +__printf(2, 3) void ntfs_printk(const struct super_block *sb, const char > *fmt, > + ...); Better would be __printf(2, 3) void ntfs_printk(const struct super_block *sb, const char *fmt, ...); etc... There's a lot of code that could be made more readable for a human.
