LAYOUTSTATS are sent every minute if IO is still happening upon a file. One limitation is that at most 4 LAYOUTSTATS calls are permitted in a compound. Had to send multiple LAYOUTSTATS operations per compound because OP_LAYOUTSTATS requires stateid and deviceid as its arguments, which makes it a per-file per-deviceid call. Cheers, Tao Peng Tao (8): pNFS: fill in nfs42_layoutstat_ops pnfs: add pnfs_report_layoutstat helper function pNFS/flexfiles: track when layout is first used pnfs/flexfiles: add ff_layout_prepare_layoutstats pnfs/flexfiles: encode LAYOUTSTATS flexfiles specific data pnfs/flexfiles: reset IO statistics upon LAYOUTSTATS success nfs42: serialize LAYOUTSTATS calls of the same file pnfs/flexfiles: report layoutstat regularly Trond Myklebust (3): NFSv.2/pnfs Add a LAYOUTSTATS rpc function pNFS/flexfiles: Remove unused struct members user_name, group_name pNFS/flexfiles: add layoutstats tracking fs/nfs/flexfilelayout/flexfilelayout.c | 448 ++++++++++++++++++++++++++++++++- fs/nfs/flexfilelayout/flexfilelayout.h | 30 ++- fs/nfs/nfs42.h | 7 +- fs/nfs/nfs42proc.c | 81 ++++++ fs/nfs/nfs42xdr.c | 122 +++++++++ fs/nfs/nfs4_fs.h | 1 + fs/nfs/nfs4proc.c | 4 +- fs/nfs/nfs4xdr.c | 1 + fs/nfs/pnfs.c | 56 +++++ fs/nfs/pnfs.h | 3 + include/linux/nfs4.h | 1 + include/linux/nfs_fs.h | 1 + include/linux/nfs_xdr.h | 43 ++++ 13 files changed, 782 insertions(+), 16 deletions(-) -- 1.8.3.1
