SVN rev 194693 on 2009-06-23 10:47:42Z by kib
MFC r192683:
In lf_advlockasync(), recheck for doomed vnode after the state->ls_lock
is acquired. In the lf_purgelocks(), assert that vnode is doomed and set
*statep to NULL before clearing ls_pending list. Otherwise, we allow for
the thread executing lf_advlockasync() to put new pending entry after
state->ls_lock is dropped in lf_purgelocks().
MFC r193931:
Do not leak the state->ls_lock after VI_DOOMED check introduced
in the r192683.
MFC r194356:
Decrement state->ls_threads when vnode appeared to be doomed.
