Find a free slot using bitmap-based allocation. Use the optimized ffz function to find a zero bit in the bitmap that indicates a free slot, starting the search from the 'lowest_free_slotid' position. If found, mark the slot as used in the bitmap, get the slot's slotid and seqid, and update max_slotid to be used by the SEQUENCE operation. Also, update lowest_free_slotid for next search. If no free slot was found the caller has to wait for a free slot (outside the scope of this function) Signed-off-by: Benny Halevy <bhalevy@panasas.com> [nfs41: find slot return slotid] Signed-off-by: Andy Adamson <andros@netapp.com> Signed-off-by: Benny Halevy <bhalevy@panasas.com> [use find_first_zero_bit for nfs4_find_slot as per review comment 21/85.] [use NFS4_MAX_SLOT_TABLE rather than NFS4_NO_SLOT] [nfs41: rpc_sleep_on slot_tbl_waitq must be called under slot_tbl_lock] Signed-off-by: Benny Halevy <bhalevy@panasas.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> |
