> Subject: [PATCH v2] fs/ntfs3: Use kernel ALIGN macros over driver specific
>
> The static checkers (Smatch) were complaining because QuadAlign() was
> buggy. If you try to align something higher than UINT_MAX it got
> truncated to a u32.
>
> Smatch warning was:
> fs/ntfs3/attrib.c:383 attr_set_size_res()
> warn: was expecting a 64 bit value instead of '~7'
>
> So that this will not happen again we will change all these macros to
> kernel made ones. This can also help some other static analyzing tools
> to give us better warnings.
>
> Patch was generated with Coccinelle script and after that some style
> issue was hand fixed.
