nfsd: prepare for supporting admin-revocation of state
The NFSv4 protocol allows state to be revoked by the admin and has error
codes which allow this to be communicated to the client.
This patch
- introduces a new state-id status SC_STATUS_ADMIN_REVOKED
which can be set on open, lock, or delegation state.
- reports NFS4ERR_ADMIN_REVOKED when these are accessed
- introduces a per-client counter of these states and returns
SEQ4_STATUS_ADMIN_STATE_REVOKED when the counter is not zero.
Decrements this when freeing any admin-revoked state.
- introduces stub code to find all interesting states for a given
superblock so they can be revoked via the 'unlock_filesystem'
file in /proc/fs/nfsd/
No actual states are handled yet.
