[PATCH 0/5] RCU-walk support for autofs

From: NeilBrown
Date: Mon Aug 18 2014 - 02:33:43 EST


Hi Ian,
Have you had a chance to run your tests in these patches yet?
I've done what testing I can think of and cannot fault them.

This set is against 3.17-rc1 and make use of the new -EISDIR handling
for d_manage() and assumes the other patches which already went in
through Andrew Morton.

I've added a section to autofs4.txt about mount namespaces, but it is
otherwise unchanged.

If I could get an {Acked,Reviewed,Tested}-By in the next few weeks so
I can send them on to Andrew I would really appreciate it.

Thanks,
NeilBrown

autofs4: allow RCU-walk to walk through autofs4.
autofs4: factor should_expire() out of autofs4_expire_indirect.
autofs4: avoid taking fs_lock during rcu-walk
autofs4: d_manage() should return -EISDIR when appropriate in rcu-walk mode.
autofs: the documentation I wanted to read
