--- Comment #4 from Mark Johnston <markj@FreeBSD.org> ---
The TDA_GEOM event sets ASTR_KCLEAR so ast_kclear() will potentially invoke
g_waitidle(), but this is not safe in arbitrary contexts.  Is this a regression
from commit c6d31b8306eb7?  I am not sure why it is necessary to set
ASTR_KCLEAR there.  Prior to that commit we did not call g_waitidle() when
tearing down a thread; only the UFS softdep AST cleanup was done.
