v4: - close more potential races in setlease code, and fix some bugs in error handling in that code. - clean up delegation setting functions, eliminating unused arguments and avoiding allocations when there has already been a delegation break - add separate spinlock for block_delegations/delegation_blocked code v3: - use alternate method for checking for delegation break races after getting a lease (just check fi_had_conflict instead) - drop file_has_lease patch -- no longer needed - move cl_revoked handling patch into this set. It means altering a few of the later patches, but it keeps the set more topically coherent v2: - move remove_stid call from nfs4_free_stid and into callers Yet another respin of the delegation rework to prepare for client_mutex removal. This fixes all of the error handling bugs I could find and should fix up the potential races between setting a delegation and having it broken. I also added some cleanup of the delegation setting code itself, moving the allocation into the nfs4_set_delegation call, so that we can avoid allocating one when we know there has already been a conflict.
