From: Zhihao Cheng Date: Mon, 28 Aug 2023 06:38:40 +0000 (+0800) Subject: ubi: fastmap: Remove unneeded break condition while filling pools X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=415e4723c4325464d489c1ef3335eb6679905471;p=linux.git ubi: fastmap: Remove unneeded break condition while filling pools Change pool filling stop condition. Commit d09e9a2bddba ("ubi: fastmap: Fix high cpu usage of ubi_bgt by making sure wl_pool not empty") reserves fastmap data PEBs after filling 1 PEB in wl_pool. Now wait_free_pebs_for_pool() makes enough free PEBs before filling pool, there will still be at least 1 PEB in pool and 1 PEB in wl_pool after doing ubi_refill_pools().
