From 70e3a85e9e6384f8876a4c1af5910a682786adbb Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Thu, 26 Jun 2014 15:38:33 -0500 Subject: btrfs-progs: add supported attr flags to btrfs(5) The chattr(1) manpage suffers from the same problems mount(1) had: many options listed, not kept up to date for various filesystems. I've submitted a manpage update for chattr(1) which says to refer to filesystem-specific manpages for supported attributes; this patch updates btrfs(5) to list the attributes supported by btrfs.
