[PATCH 0/1] MR9861: ntdll/unix/file.c: added new xattr for marking directories as readonly

[Rayan Halder (＠rayanh)]

On Windows, directories marked as readonly do not behave as readonly directories on linux.
Readonly has no effect on windows but on querying for attributes, windows shows the directory to be readonly.

To simulate this behaviour, an xattribute is being used to mark a directory as readonly.
