xattr.7: Rename from attr.7
...
"xattr" is a more meaningful name than "attr" (it resonates
with the names of the system calls), so as long as we are
moving the page to a new section, we'll change the name as well,
and retain an acl(5) link so that old references remain valid.

attr.7: Document EA limits for Btrfs
...
From experimentation, I found a 16kB limit on name + value +
overhead bytes. Digger deeper, I see that
https://btrfs.wiki.kernel.org/index.php/Project_ideas#Unlimited_extended_attributes
says:
Unlimited extended attributes
Not claimed — no patches yet — Not in kernel yet
Currently size of value of an extended attribute must fit into
inline space (~3900 on 4k leaf size), while other filesystems
do not limit the size. Add a new b-tree item to hold the xattr
value in extents.
And reading mkfs.btrfs(8) reveals that the default node (AKA leaf)
size is 16kB.
