Subject: f2fs: fix to convert log type to segment data type correctly
X-Git-Tag: v6.13-rc1~77^2~18
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=51d3d952c5084393d89cce0b951bb5f18eb97bb1;p=thirdparty%2Fkernel%2Flinux.git

f2fs: fix to convert log type to segment data type correctly

This patch introduces a new helper log_type_to_seg_type() to convert
log type to segment data type, and uses it to clean up opened codes
in build_curseg(), and also it fixes to convert log type before use
in do_write_page().
