+Subject: [PATCH] tests: flock: increase "wait for flock child" timeout
+
+The flock test launches "flock ... bash -c '... sleep 3 ...'" in the
+background and then waits for flock to spawn its child using a hardcoded
+"timeout 1s" around a pgrep poll loop. That 1 second only covers process
+startup, so it is purely a function of host speed. Under emulation (e.g.
+qemuriscv64 under TCG) spawning the shell and flock can exceed 1s, so
+pgrep does not see the child in time and the test aborts with "timeout
+waiting for flock child", failing intermittently.
+
+Increase the timeout to 30s. The loop exits as soon as the child
+appears, so this does not slow down fast hosts; it only adds headroom on
+slow/emulated targets.
+
+Upstream-Status: Submitted [https://github.com/util-linux/util-linux/pull/4639]
