hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8PGC4
--------------------------------
for performance reasons, hulk 6.6 do not use OPTIMIZE_INLINING. it using gnu_inline attribute causing inline functions not really inline, which introducing performance issues,so we make it editable(default disable) and adapt some link conflicting functions.
