From: Nghia Le Date: Mon, 25 Oct 2021 22:18:03 +0000 (+0700) Subject: ext4: remove useless resetting io_end_size in mpage_process_page() X-Git-Tag: v5.19~1455^2~9 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=effc5b3b0d20ffcb692f107cd347289bfcd6890b;p=mirror_ubuntu-kernels.git ext4: remove useless resetting io_end_size in mpage_process_page() The command "make clang-analyzer" detects dead stores in mpage_process_page() function. Do not reset io_end_size to 0 in the current paths, as the function exits on those paths without further using io_end_size.
