From: Uros Bizjak Date: Sun, 8 Mar 2026 17:12:35 +0000 (+0100) Subject: x86/local: Remove trailing semicolon from _ASM_XADD in local_add_return() X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=ceea7868b594ccf376562af40b9463d9f2fb7dd0;p=thirdparty%2Fkernel%2Flinux.git x86/local: Remove trailing semicolon from _ASM_XADD in local_add_return() Remove the trailing semicolon from the inline assembly statement in local_add_return(). The _ASM_XADD macro already expands to a complete instruction, making the extra semicolon unnecessary. More importantly, the stray semicolon causes GCC to treat the inline asm as containing multiple instructions, which can skew its internal instruction count estimation and affect optimization heuristics. No functional change intended.
