Seems the ioctl is only way to implement chattr(). I propose to add all these flags to os.chflags() and to gain its support in Linux.

bpo-39533 is a related issue that seeks to support the Linux statx() system call. A statx record includes an stx_attributes field, which supports the following file attributes that can be set with chattr:

    [a]ppend    : STATX_ATTR_APPEND
    [c]ompressed: STATX_ATTR_COMPRESSED
    no [d]ump   : STATX_ATTR_NODUMP
    [i]mmutable : STATX_ATTR_IMMUTABLE
    da[x]       : STATX_ATTR_DAX (5.8)

and the following read-only file attributes that can be listed with lsattr:

    [E]ncrypted : STATX_ATTR_ENCRYPTED
    [V]erity    : STATX_ATTR_VERITY (5.5)
