mainline inclusion from mainline-v5.15 commit fa3cacf544636b2dc48cfb2f277a2071f14d66a2 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4G67J?from=project-issue CVE: NA
----------------------------------------------------------------------
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.
Coccinelle script:
