Hi,

I've made some updates on the wiki and I'd like a technical review for
correctness. This particular topic is already confusing - some
unnecessary sarcasm made it even more so:
https://btrfs.wiki.kernel.org/index.php/FAQ#Why_does_df_show_incorrect_free_space_for_my_RAID_volume.3F

I posted some patches in order to address this issue. However these
aren't integrated (yet). At the end I think that I reached a general
consensus about the wording. A general description is here [1]. The
patch related to man page is here [2], which can help about the wording.

I hope that it will help your work.

Due to the terms "used" and "allocated" in the wiki, viric in #btrfs
made the good suggestion that we could adjust the show and df output
with more intuitive language:

Before I git a patch together, please let me know if there are any good
reasons why we wouldn't want to make such a change.

(13:31:29) viric: zatricky: "devid ... used" are allocated data, while
"FS bytes used" is the sum of used bytes, isn't it?
(13:33:28) zatricky: viric: correct
(13:33:52) viric: zatricky: maybe the devid lines could be changed
s/used/allocated/
(13:34:37) zatricky: viric: that's a good idea - would make it more
intuitive
(13:35:29) viric: the same way, 'btrfs fi df' could change
s/total/allocated
^ GMT+2 ;)

Thanks
