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, it's possible that you'll also need
+ this option as there are a number of Linux distros that require
+ POSIX ACL support under /dev for certain features to work properly.
+ For example, some distros need this feature for ALSA-related /dev
+ files for sound to work properly. In short, if you're not sure,
+ 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.
