Subject: xfs: remove experimental tag for reverse mapping
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=76883f7988e6d06a97232e979bc7aaa7846a134b;p=openwrt%2Fstaging%2Fblogic.git

xfs: remove experimental tag for reverse mapping

Reverse mapping has had a while to soak, so remove the experimental tag.
Now that we've landed space metadata cross-referencing in scrub, the
feature actually has a purpose.

Reject rmap filesystems with an rt device until the code to support it
is actually implemented.
