Subject: WARNING during btrfs send, kernel 4.1-rc1
Date: Thu, 30 Apr 2015 00:15:00 -0400 [thread overview]
Message-ID: <5541AC44.3080008@gmail.com> (raw)
Sand & receive from the same machine, from a read-only mount to a
freshly formatted fs. Aside from the warning everything appears to
be working correctly, but since this is the latest btrfs code it
needed reporting.
I'll probably have another opportunity to test this again, since I'm
blowing up my array repeatedly trying to track down a bcache bug.
line number translates to:
/*
* This is done when we lookup the root, it should already be complete
* by the time we get here.
*/
WARN_ON(send_root->orphan_cleanup_state != ORPHAN_CLEANUP_DONE);
