From 3efbe13e361acfd163fd1a2466e4fb9bed7dc1b0 Mon Sep 17 00:00:00 2001 From: Lukas Bulwahn Date: Mon, 22 Jan 2024 10:25:04 +0100 Subject: [PATCH] mempolicy: clean up minor dead code in queue_pages_test_walk() Commit 2cafb582173f ("mempolicy: remove confusing MPOL_MF_LAZY dead code") removes MPOL_MF_LAZY handling in queue_pages_test_walk(), and with that, there is no effective use of the local variable endvma in that function remaining. Remove the local variable endvma and its dead code. No functional change. This issue was identified with clang-analyzer's dead stores analysis.
