This patch series adds support for session dynamic slot management
in accordance with Section 2.10.6.1 of RFC5661.
By tracking the sr_target_highest_slotid and sr_highest_slotid in the
server's replies to our SEQUENCE operations, we can figure out when
it is safe to increase the number of RPC requests that go in parallel
to the server, and when we should decrease that number.
Trond Myklebust (20):
NFSv4.1: Don't confuse CREATE_SESSION arguments and results
NFSv4.1: Adjust CREATE_SESSION arguments when mounting a new
filesystem
NFSv4.1: We must bump the clientid sequence number after
CREATE_SESSION
NFSv4.1: nfs4_alloc_slots doesn't need zeroing
NFSv4.1: clean up nfs4_recall_slot to use nfs4_alloc_slots
NFSv4.1: Shrink struct nfs4_sequence_res by moving sr_renewal_time
NFSv4.1: Shrink struct nfs4_sequence_res by moving the session
pointer
NFSv4.1: Label each entry in the session slot tables with its slot
number
NFSv4.1: Simplify struct nfs4_sequence_args too
NFSv4.1: Simplify slot allocation
NFSv4.1: Clean up nfs4_free_slot
NFSv4.1: Ensure that the client tracks the server
target_highest_slotid
NFSv4.1: Reset the sequence number for slots that have been
deallocated
NFSv4.1: Fix nfs4_callback_recallslot to work with dynamic slot
allocation
NFSv4.1: Don't confuse target_highest_slotid and max_slots in
cb_recall_slot
NFSv4.1: Allow the server to recall all but one slot
NFSv4.1: Support dynamic resizing of the session slot table
NFSv4.1: Allow SEQUENCE to resize the slot table on the fly
NFSv4.1: Remove the state manager code to resize the slot table
NFSv4.1: CB_RECALL_SLOT must schedule a sequence op after updating
targets
