Subject: tmpfs: expand "help" to explain value of TMPFS_POSIX_ACL
From: "Robert P. J. Day" <rpjday@xxxxxxxxxxxxxx>
Expand the fs/Kconfig "help" info to clarify why it's a bad idea to
deselect the TMPFS_POSIX_ACL config variable.

- POSIX Access Control Lists (ACLs) support permissions for users and
- groups beyond the owner/group/world scheme.
+ POSIX Access Control Lists (ACLs) support additional access rights
+ for users and groups beyond the standard owner/group/world scheme,
+ and this option selects support for ACLs specifically for tmpfs
+ filesystems.
+
+ If you've selected TMPFS, you almost certainly want this option
+ as well since a number of user space features (e.g., ALSA sound)
+ require POSIX ACL support under /dev to work properly. In other
+ words, if you're not sure and you have no *compelling* reason to
+ deselect this feature, say Y.
To learn more about Access Control Lists, visit the POSIX ACLs for
Linux website <http://acl.bestbits.at/>.
- If you don't know what Access Control Lists are, say N.
