+ err = grub_disk_read (disk, EROFS_SUPER_OFFSET >> GRUB_DISK_SECTOR_BITS, 0, + sizeof (sb), &sb); + if (grub_errno == GRUB_ERR_OUT_OF_RANGE) + grub_error (GRUB_ERR_BAD_FS, "not a valid erofs filesystem");OUT_OF_RANGE is already treated the same asBAD_FS in context of opening a file
Sorry, I didn't fully understand that. I copied similar logic from the ext2 driver (fs/ext2.c).
Are you suggesting that I should remove the error code conversion here? All the other suggestions are great, I will reply in subsequent emails. Thanks, Yifan Zhao
