Hi Hirofumi-san, > It may be ok. However, of course, it should consider other than > ascii. Well, I think the patch should be allow only perfect 8.3 name in > vfat_create_shortname(). (i.e. is_shortname && base/ext_info.valid) ok, so something like this in vfat_create_shortname() ? #ifdef CONFIG_VFAT_NO_CREATE_WITH_LONGNAMES if (is_shortname == 0 || !(base_info.valid && ext_info.valid)) return -ENAMETOOLONG; shortname_flags = VFAT_SFN_CREATE_WINNT; #endif that still means that creating a file ShortNam.TxT actually creates shortnam.txt on disk. Will the case-insensitive vfat_cmpi used as d_compare cope OK with that?
