Subject: xfs: don't flag quota rt block usage on rtreflink filesystems
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=cca34a305446f0eeea7c6c76bbb01ecf58be9cbc;p=users%2Fjedix%2Flinux-maple.git

xfs: don't flag quota rt block usage on rtreflink filesystems

Quota space usage is allowed to exceed the size of the physical storage
when reflink is enabled.  Now that we have reflink for the realtime
volume, apply this same logic to the rtb repair logic.
