Subject: mds/scrub: write root inode backtrace at creation
X-Git-Tag: v17.1.0~1760^2
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=7757f3ea3c1aebb71fd34454751634a822c021bd;p=ceph-ci.git

mds/scrub: write root inode backtrace at creation

Write root inode backtrace as soon as it is created;
Unwritten backtrace always caused scrub to fail for root inode.
