Btrfs filesystem resize syntax

What happened to the patches to --help and man pages that did explain t= he=20
multi-device use-case:

btrfs filesystem resize [<devid>:][+/-]<newsize>[gkm]|max <filesystem>

(the <devid>: bit is missing)
It is explained on the wiki:=20
http://btrfs.ipv5.de/index.php?title=3DBtrfs(command)
but I don't see those patches in Chris btrfs-progs tree.

Regards,

Hi all,

I am resubmitting an old patch, which has the aim to document the <devid> parameter of the btrfs filesystem resize command.

The patch is against the Mason master repo.

Hugo, Chris, please apply
