Eric, Yeah, it's a little bit strange to include that patch into mount API series, now, I realize that rebasing huge change to a minor fix is not necessary, anyway, let me focus on reviewing, and pickup that patch after mount API series be merged. :P Thanks, > > Thanks, > -Eric > _______________________________________________ Linux-f2fs-devel mailing list Linux-f2fs-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linux-f2fs-devel
