| |
Hello!
The following miscellaneous fixes come before the infamous ->gp_seq conversion:
1. Add debugging info to the assertion detecting tasks queued on the ->blkd_tasks list at unexpected times.
2. Use the proper lockdep annotation in dump_blkd_tasks(), courtesy of Boqun Feng.
3. Exclude near-simultaneous RCU CPU stall warnings, thus reducing the probability of interleaved (and thus inscrutable) warnings.
4. Add diagnostics for failure to respond to a request for a new grace period.
5. Make rcu_gp_cleanup() write only once to ->gp_flags.
Thanx, Paul
