At the moment, BTRFS is limited to xattrs that fit inline in the 
metadata nodes (so ~3900 bytes for a 4k leafsize).

XFS, however, isn't the only Linux filesystem that supports xattrs that 
size.  Assuming that you are using a recent kernel, you can also use 
such xattrs on at least:
 * XFS
 * JFS
 * ext4
 * reiserfs (I think, not 100% certain about this one though)
 * OCFS2 (even though it is technically a cluster fs, it can be run 
single node without the clustering)
 * ZFS (IIRC, ZFS supports unlimited xattr size)
 * NTFS (no limit on xattr size, though you should use NTFS-3G instead 
of the in-kernel driver)
 * SquashFS (read-only)
 * HFS+ (Also no limit on xattr size)
Of these, I'd personally suggest using XFS unless you need to be able to 
shrink the filesystem, in which case I'd suggest ext4.
