 .SH FILESYSTEM DIFFERENCES
 The kernel and the filesystem may place limits on the maximum number
 and size of extended attributes that can be associated with a file.
+Some file systems, such as ext2/3 and reiserfs, require the filesystem
+to be mounted with the
+.B user_xattr
+mount option in order for extended user attributes to be used.
+.PP
+In the current ext2, ext3 and ext4 filesystem implementations, each
+extended attribute must fit on a single filesystem block (1024, 2048

+In the XFS and reiserfs filesystem implementations, there is no
