This was a regression around July 3; there was no regression test at the time. [615f2867854c186a37cb2e2e5a2e13e9ed4ab0df] Btrfs-progs: cleanup similar code in open_ctree_* and close_ctree broke it. Patches were sent to the list to fix it on July 17, https://patchwork.kernel.org/patch/2828820/ but they haven't been merged into the main repo. I sent a regression test for it to the list on Aug 4, but nobody reviewed it, so it hasn't been merged into the test suite, either. Winning all around! -Eric -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
