    Yes, chflags() is not supported by linux directly. But actually, Linux supports chflags functionality:

    https://stackoverflow.com/questions/34176464/why-os-chflags-doesnt-work-under-linux

    through

    ioctl (fd, EXT2_IOC_SETFLAGS, <BITMASK_OF_FLAGS>)

    Judging by the ioctl name, this is ext2/ext3/ext4 specific?

    Well, it seems, you are right.

    But there are another ioctls (maybe they are the same, I haven't checked):

    FS_IOC_SETFLAGS
    FS_IOC_GETFLAGS

    On Ubuntu 16.04 I get the following values:
    EXT2_IOC_SETFLAGS = 0x40086602, FS_IOC_GETFLAGS = 0x80086601

    Uh, of course, we care about SETFLAGS here. Which gives:
    EXT2_IOC_SETFLAGS = 0x40086602, FS_IOC_SETFLAGS = 0x40086602
