[GIT PULL] afs

[Christian Brauner <brauner@kernel.org>]

Hey Linus,

/* Summary */

This contains afs updates for this cycle:

Features:

- dynamic root improvements:

  - Create an /afs/.<cell> mountpoint to match the /afs/<cell>
    mountpoint when a cell is created.

  - Add some more checks on cell names proposed by the user to prevent
    dodgy symlink bodies from being created.  Also prevent rootcell from
    being altered once set to simplify the locking.

  - Change the handling of /afs/@cell from being a dentry name
    substitution at lookup time to making it a symlink to the current
    cell name and also provide a /afs/.@cell symlink to point to the
    dotted cell mountpoint.

Fixes:

- Fix the abort code check in the fallback handling for the
  YFS.RemoveFile2 RPC call.

- Use call->op->server() for oridnary filesystem RPC calls that have an
  operation descriptor instead of call->server()
