Alexander Aring 700ed41bf6 dlm: fix user space lkb refcounting ... [ Upstream commit 2ab3d705ca5d4f7ea345a21c3da41a447a549649 ] This patch fixes to check on the right return value if it was the last callback. The rv variable got overwritten by the return of copy_result_to_user(). Fixing it by introducing a second variable for the return value and don't let rv being overwritten.
