X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=3c70280575fc56b12e67d416292cf2b14bb91e75;p=users%2Fhch%2Fxfsprogs.git

xfs: attach rtgroup objects to btree cursors

Make it so that we can attach realtime group objects to btree cursors.
This will be crucial for enabling rmap btrees in realtime groups.
