[PATCH 04/11] Btrfs-progs: don't fail on log tree opening with PARTIAL

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We were failing to fsck a volume because we couldn't open the log tree, which is
not helpful.  Make us skip erroring out if we are using OPEN_CTREE_PARTIAL since
it isn't a mandatory tree.  Thanks,
