Currently perf has supported a mode to query inline stack. It works well for finding the user space inline function but it doesn't work for finding kernel inline function due to some unnecessary checking.
This patch removes these unnecessary checking. Now the kernel inline function can be reported. For example, perf report --inline -g func --stdio |--46.19%--do_huge_pmd_anonymous_page | do_huge_pmd_anonymous_page (inline) | __do_huge_pmd_anonymous_page (inline) | __SetPageUptodate (inline) | __set_bit (inline) The result is compared with the output of addr2line. They are match.
