[issue42939] Linux's chattr i.e. ioctl(FS_IOC_SETFLAGS) is not supported in os.chflags()

[Eryk Sun]

Eryk Sun  added the comment:

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)

[Марк Коренберг]

New submission from Марк Коренберг :

https://man7.org/linux/man-pages/man2/ioctl_iflags.2.html

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.
