From b4b45994a9ba02d575625e3b1076c337be7d4861 Mon Sep 17 00:00:00 2001 From: Zhihao Cheng Date: Mon, 13 Nov 2023 17:48:11 +0800 Subject: ubiattach: introduce disable_fm in UBI_IOCATT The ioctl UBI_IOCATT has been extended with disable_fm parameter after [1]. This parameter is used for disabling fastmap for target ubi device. If 'disable_fm' is set, ubi doesn't create new fastmap even the module param 'fm_autoconvert' is set, and existed old fastmap will be destroyed after attaching process. A simple test case in [2].
