While we already do this for open and lock state, we have not been doing so for all the delegations. v2: nfs_v4_2_minor_ops needs to set .test_and_free_expired too v3: Now with added lock revoke fixes and close/delegreturn/locku fixes Trond Myklebust (12): NFSv4.1: Don't deadlock the state manager on the SEQUENCE status flags NFSv4.1: Don't check delegations that are already marked as revoked NFSv4.1: Allow test_stateid to handle session errors without waiting NFSv4.1: Add a helper function to deal with expired stateids NFSv4.x: Allow callers of nfs_remove_bad_delegation() to specify a stateid NFSv4.1: Test delegation stateids when server declares "some state revoked" NFSv4.1: Deal with server reboots during delegation expiration recovery NFSv4.1: Don't recheck delegations that have already been checked NFSv4.1: Allow revoked stateids to skip the call to TEST_STATEID NFSv4.1: Ensure we always run TEST/FREE_STATEID on locks NFSv4.1: FREE_STATEID can be asynchronous NFSv4.1: Ensure we call FREE_STATEID if needed on close/delegreturn/locku fs/nfs/delegation.c | 153 ++++++++++++++++++- fs/nfs/delegation.h | 6 +- fs/nfs/flexfilelayout/flexfilelayout.c | 2 +- fs/nfs/nfs4_fs.h | 5 +- fs/nfs/nfs4proc.c | 258 ++++++++++++++++++++++----------- fs/nfs/nfs4session.h | 1 + fs/nfs/nfs4state.c | 29 ++-- include/linux/nfs4.h | 1 + 8 files changed, 348 insertions(+), 107 deletions(-) -- 2.7.4
