Extended attributes limit in Linux

[Sun_Blood]

Hello,

If I understands it correctly XFS don't have a limit to the size of
extended attributes(EA) but Linux impose a limit at 64k.
What I am trying to do is build a backup server that our Apple computers
will use together with rsync to backup files to. The problem I face is that
Apple HFS+ don't have a limit to EA so it has files with more then 64k of
EA in it.

The Linux Kernel has a limit imposed to it in include/linux/limits.h

> #define XATTR_SIZE_MAX 65536    /* size of an extended attribute value
> (64k) */
>
#define XATTR_LIST_MAX 65536    /* size of extended attribute namelist
> (64k) */
>

Changing this values feels unsafe because they will be system wide.

Is the any possibility to combine Linux + XFS to make a backup that works
with EA or is this more a question for kernel.org?

Thanks.
