Re: [PATCH] XATTR issues on JFFS2

[KaiGai Kohei <kaigai@ak.jp.nec.com>]

Hello,

In recent days, I'm interrested in XATTR support in JFFS2.

I have started a discussion about it on MTD-ML.
http://lists.infradead.org/pipermail/linux-mtd/2005-August/013415.html

By ML-archive, an implementation use hidden-file to store XATTR was
rejected finally. Thus, I adopted different approach.
This implementation added two new node types JFFS2_NODETYPE_XATTR
and JFFS2_NODETYPE_XREF for XATTR representation.

If your comment can be gotten, I'm so glad.

# I think it's not appropriate to discuss JFFS2 at SELinux-ML.
# Please comment it on MTD-ML, if possible.

Thanks,

*---- Example of use ------------

In my desktop PC, "fs_use_xattr jffs2 system_u:object_r:fs_t;"
was configured. :)
