Pull vfs afs updates from Christian Brauner:
"This contains the work for afs for this cycle:
- Fix an occasional hang that's only really encountered when
rmmod'ing the kafs module
- Remove the "-o autocell" mount option. This is obsolete with the
dynamic root and removing it makes the next patch slightly easier
- Change how the dynamic root mount is constructed. Currently, the
root directory is (de)populated when it is (un)mounted if there are
cells already configured and, further, pairs of automount points
have to be created/removed each time a cell is added/deleted
This is changed so that readdir on the root dir lists all the known
cell automount pairs plus the @cell symlinks and the inodes and
dentries are constructed by lookup on demand. This simplifies the
cell management code
- A few improvements to the afs_volume and afs_server tracepoints
- Pass trace info into the afs_lookup_cell() function to allow the
trace log to indicate the purpose of the lookup
- Remove the 'net' parameter from afs_unuse_cell() as it's
superfluous
- In rxrpc, allow a kernel app (such as kafs) to store a word of
information on rxrpc_peer records
- Use the information stored on the rxrpc_peer record to point to the
afs_server record. This allows the server address lookup to be done
away with
- Simplify the afs_server ref/activity accounting to make each one
self-contained and not garbage collected from the cell management
work item
- Simplify the afs_cell ref/activity accounting to make each one of
these also self-contained and not driven by a central management
work item
The current code was intended to make it such that a single timer
for the namespace and one work item per cell could do all the work
required to maintain these records. This, however, made for some
sequencing problems when cleaning up these records. Further, the
attempt to pass refs along with timers and work items made getting
it right rather tricky when the timer or work item already had a
ref attached and now a ref had to be got rid of"
