From a791b1565f828f926a54f1f5a612890ce0f00e6f Mon Sep 17 00:00:00 2001 From: Chen Gang Date: Sat, 4 Oct 2014 21:11:31 +0800 Subject: [PATCH] um: kernel: ksyms: Export symbol syscall() for fixing modpost issue syscall() is implemented in libc.so/a (e.g. for glibc, in "syscall.o"), so for normal ".o" files, it is undefined, neither can be found within kernel wide, so will break modpost. Since ".o" files is OK, can simply export 'syscall' symbol, let modpost know about that, then can fix this issue. The related error (with allmodconfig under um): MODPOST 1205 modules ERROR: "syscall" [fs/hostfs/hostfs.ko] undefined!
