From 5f4c33d0e0abd929d5eee98ba22c0a332b9d3457 Mon Sep 17 00:00:00 2001 From: Alexandre Besnard Date: Mon, 4 Apr 2022 17:50:14 +0200 Subject: [PATCH] cmd: ubi.c: skip part command if right partition is already attached Attaching a UBI partition may take a while, since scanning the memory is required. It thus makes sense to avoid a detach/scan/attach cycle when the right partition is already attached, and let the calling process call 'detach' beforehand if it needs it. This commit checks for the currently attached UBI partition, and skips reattaching if not needed, showing an information.
