| Series | [1/5] selftests: vdso: Fix vDSO name for powerpc | expand |
Hi Shuah, No 0/5 patch, so replying to the first one. These are fixes to the vDSO selftests that Christophe is ostensibly providing as a preamble to his work porting vgetrandom to PPC. Do you mind if I take these via my random tree so his PPC vgetrandom code can go on top of it? Jason
