From: Zhang Yi Date: Thu, 1 Sep 2022 13:34:56 +0000 (+0800) Subject: isofs: replace ll_rw_block() X-Git-Tag: v6.1-rc5~170^2~470 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0ed48061887f603b33b7dcb9075cbfaaa8d02723;p=platform%2Fkernel%2Flinux-starfive.git isofs: replace ll_rw_block() ll_rw_block() is not safe for the sync read path because it cannot guarantee that submitting read IO if the buffer has been locked. We could get false positive EIO return from zisofs_uncompress_block() if he buffer has been locked by others. So stop using ll_rw_block(), switch to sync helper instead.
