From e4514111ebb6df5f22a0769a9dfb2338b9c6c81a Mon Sep 17 00:00:00 2001 From: Jiang XueQian Date: Sat, 30 Aug 2025 17:02:59 +0800 Subject: [PATCH] zramctl: ignore ENOENT when setting max_comp_streams The `max_comp_streams` attribute of zram devices has been deprecated and all writes were silently ignored by the kernel since 2016. It was finally removed in 6.15, causing zramctl to fail on ENOENT, when it should just ignore the error.
