      NFSv4.1: Clean ups and bugfixes for the pNFS read/writeback/commit code · 8dd37758
      Trond Myklebust 提交于
      Move more pnfs-isms out of the generic commit code.
      
      Bugfixes:
      
      - filelayout_scan_commit_lists doesn't need to get/put the lseg.
        In fact since it is run under the inode->i_lock, the lseg_put()
        can deadlock.
      
      - Ensure that we distinguish between what needs to be done for
        commit-to-data server and what needs to be done for commit-to-MDS
        using the new flag PG_COMMIT_TO_DS. Otherwise we may end up calling
        put_lseg() on a bucket for a struct nfs_page that got written
        through the MDS.
      
      - Fix a case where we were using list_del() on an nfs_page->wb_list
        instead of list_del_init().
      
      - filelayout_initiate_commit needs to call filelayout_commit_release
        on error instead of the mds_ops->rpc_release(). Otherwise it won't
        clear the commit lock.
      
      Cleanups:
      
      - Let the files layout manage the commit lists for the pNFS case.
        Don't expose stuff like pnfs_choose_commit_list, and the fact
        that the commit buckets hold references to the layout segment
        in common code.
      
      - Cast out the put_lseg() calls for the struct nfs_read/write_data->lseg
        into the pNFS layer from whence they came.
      
      - Let the pNFS layer manage the NFS_INO_PNFS_COMMIT bit.

      NFSv4.1: unify pnfs_pageio_init functions · dfed206b
      Benny Halevy 提交于
      Use common code for pnfs_pageio_init_{read,write} and use
      a common generic pg_test function.
      
      Note that this function always assumes the the layout driver's
      pg_test method is implemented.

      pnfs: Use byte-range for layoutget · fb3296eb
      Benny Halevy 提交于
      Add offset and count parameters to pnfs_update_layout and use them to get
      the layout in the pageio path.
      
      Order cache layout segments in the following order:
      * offset (ascending)
      * length (descending)
      * iomode (RW before READ)
      
      Test byte range against the layout segment in use in pnfs_{read,write}_pg_test
      so not to coalesce pages not using the same layout segment.
