Revision de5604231ce4bc8db1bc1dcd27d8540cbedf1518 authored by Nick Piggin on 01 February 2010, 11:24:18 UTC, committed by Linus Torvalds on 02 February 2010, 20:50:47 UTC
RCU list walking of the per-cpu vmap cache was broken. It did not use RCU primitives, and also the union of free_list and rcu_head is obviously wrong (because free_list is indeed the list we are RCU walking). While we are there, remove a couple of unused fields from an earlier iteration. These APIs aren't actually used anywhere, because of problems with the XFS conversion. Christoph has now verified that the problems are solved with these patches. Also it is an exported interface, so I think it will be good to be merged now (and Christoph wants to get the XFS changes into their local tree).
