If this flag is set, the extents returned will describe the inodes
extended attribute lookup tree, instead of it's data tree.
What is this for? The meaning of the xattr tree sounds rather
filesystem specific to me.
This is to return the location of the xattr blocks for the inode.
Jamie is completely right that this is file system specific. It only
has a meaning for file systems which use an "xattr tree" whatever that
is. At a guess that is just XFS? It seems a bit odd to have such a
file system specific flag in a generic interface. On the other hand
given the resistance to exposing named streams properly in Linux I
guess this is the only thing you can do to get this information so I
have no objections.
Best regards,
