| H A D | security.c | a0753c29 Mon May 20 02:48:46 CDT 2019 David Howells <dhowells@redhat.com> afs: Support RCU pathwalk
Make afs_permission() and afs_d_revalidate() do initial checks in RCU-mode
pathwalk to reduce latency in pathwalk elements that get done multiple
times. We don't need to query the server unless we've received a
notification from it that something has changed or the callback has
expired.
This requires that we can request a key and check permits under RCU
conditions if we need to.
