[Cluster-devel] [PATCH dlm/next 1/3] fs: change ast and bast trace order

[Alexander Aring]

This patch changes the order to call trace functionality before calling
the traced callback. The intention is always to see at first that a dlm
callback occurred and then optionally see dlm user traces in the ast or
bast callback. Currently the behaviour is vice versa, the user sees that
dlm ast or bast callback occurred after the dlm user callback for ast or
bast was called.
