From dbf53f7597be11ffc18b16444a1ffc7d7b76746e Mon Sep 17 00:00:00 2001 From: Tianjia Zhang Date: Wed, 24 Feb 2021 12:04:46 -0800 Subject: mm/mprotect.c: optimize error detection in do_mprotect_pkey() Obviously, the error variable detection of the if statement is for the mprotect callback function, so it is also put into the scope of calling callbck. This is a cleanup which makes this site consistent with the rest of this function's error handling.
