Subject: klp-build: Reject patches to vDSO
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=d8c3e262361b04984f0322ce5b88ea52dab37318;p=thirdparty%2Fkernel%2Flinux.git

klp-build: Reject patches to vDSO

vDSO code runs in userspace and can't be livepatched.  Such patches also
cause spurious "new function" errors due to generated files like
vdso*-image.c having unstable line numbers across builds.
