I am working off of the latest xfs tree and am having issues with dmapi.
I load xfs-dmapi and then on a mount I get a segfault. Upon turning on
debugging, I found that the fs_type that the fs is mounting (xfs) in
this case does not find a match to the ftype_list. The debug shows that
the list is fine but there probably is an issue with the super block
being passed by the xfs send_mount_event. I saw one other guy mention
this issue in the archive but I did'nt see an answer. Let me know if
somebody can help.
Thanks.
