From 2425614638a798e55e79e1b1f9b8d84567769311 Mon Sep 17 00:00:00 2001 From: Zhihao Cheng Date: Mon, 13 Nov 2023 17:48:12 +0800 Subject: ubiattach: introduce need_resv_pool in UBI_IOCATT The ioctl UBI_IOCATT has been extended with need_resv_pool parameter in [1]. This parameter is used for deciding whether to reserve PEBs for filling pool/wl_pool for target ubi device. This parameter will be effective when fastmap is enabled, which will slow down the frequency of updating fastmap by filling more free PEBs in pool/wl_pool. See details in [2].
