[PATCH v3 0/4] fixes, cleanups for rcu/dev

[Joel Fernandes]

Hi Paul,

Here are some patches reworked with a few comments on few of the patches
from previous series: https://lkml.org/lkml/2018/5/13/296

4/4 is a new addition which fixes a potential issue.

Please disregard the v2, and consider this v3 instead, since that v2 was
a pure patch generation mess. thanks!

Joel Fernandes (4):
  rcu: Add comment documenting how rcu_seq_snap works
  rcu: Cleanup the variables used to request a new grace period
  rcu: Use better variable names in funnel locking loop
  rcu: Unlock non-start node only after accessing its gp_seq_needed
