The patch titled Subject: fat: clean up xlate_to_uni() has been removed from the -mm tree. Its filename was fat-clean-up-xlate_to_uni.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ From: Namjae Jeon <linkinjeon@xxxxxxxxx> Subject: fat: clean up xlate_to_uni() xlate_to_uni() is called by vfat_build_slots() with sbi->nls_io as the final argument. nls_io can never be null at this point because the check is already being done in fat_fill_super() wherein the mount fails if it is null.
