      alpha: Fix build around srm_sysrq_reboot_op · 5cd221e8
      Joerg Roedel 提交于
      The patch introducing the struct was probably never compile tested,
      because it sets a handler with a wrong function signature. Wrap the
      handler into a functions with the correct signature to fix the build.

      NFS: Fix direct WRITE throughput regression · ba838a75
      Chuck Lever 提交于
      I measured a 50% throughput regression for large direct writes.
      
      The observed on-the-wire behavior is that the client sends every
      NFS WRITE twice: once as an UNSTABLE WRITE plus a COMMIT, and once
      as a FILE_SYNC WRITE.
      
      This is because the nfs_write_match_verf() check in
      nfs_direct_commit_complete() fails for every WRITE.
      
      Buffered writes use nfs_write_completion(), which sets req->wb_verf
      correctly. Direct writes use nfs_direct_write_completion(), which
      does not set req->wb_verf at all. This leaves req->wb_verf set to
      all zeroes for every direct WRITE, and thus
      nfs_direct_commit_completion() always sets NFS_ODIRECT_RESCHED_WRITES.
      
      This fix appears to restore nearly all of the lost performance.

      nfs: set invalid blocks after NFSv4 writes · 3a39e778
      Zheng Bin 提交于
      Use the following command to test nfsv4(size of file1M is 1MB):
      mount -t nfs -o vers=4.0,actimeo=60 127.0.0.1/dir1 /mnt
      cp file1M /mnt
      du -h /mnt/file1M  -->0 within 60s, then 1M
      
      When write is done(cp file1M /mnt), will call this:
      nfs_writeback_done
        nfs4_write_done
          nfs4_write_done_cb
            nfs_writeback_update_inode
              nfs_post_op_update_inode_force_wcc_locked(change, ctime, mtime
      nfs_post_op_update_inode_force_wcc_locked
         nfs_set_cache_invalid
         nfs_refresh_inode_locked
           nfs_update_inode
      
      nfsd write response contains change, ctime, mtime, the flag will be
      clear after nfs_update_inode. Howerver, write response does not contain
      space_used, previous open response contains space_used whose value is 0,
      so inode->i_blocks is still 0.
      
      nfs_getattr  -->called by "du -h"
        do_update |= force_sync || nfs_attribute_cache_expired -->false in 60s
        cache_validity = READ_ONCE(NFS_I(inode)->cache_validity)
        do_update |= cache_validity & (NFS_INO_INVALID_ATTR    -->false
        if (do_update) {
              __nfs_revalidate_inode
        }
      
      Within 60s, does not send getattr request to nfsd, thus "du -h /mnt/file1M"
      is 0.
      
      Add a NFS_INO_INVALID_BLOCKS flag, set it when nfsv4 write is done.

      NFS: remove redundant initialization of variable result · 86b93667
      Colin Ian King 提交于
      The variable result is being initialized with a value that is never read
      and it is being updated later with a new value.  The initialization is
      redundant and can be removed.

      sunrpc: add missing newline when printing parameter 'auth_hashtable_size' by sysfs · 2ac3ddc7

      follows. It is better to add a newline for easy reading.

      obvious I/O error.

      SUNRPC: Set SOFTCONN when destroying GSS contexts · 841a2ed9
      Chuck Lever 提交于
      Move the RPC_TASK_SOFTCONN flag into rpc_call_null_helper(). The
      only minor behavior change is that it is now also set when
      destroying GSS contexts.
      
      This gives a better guarantee that gss_send_destroy_context() will
      not hang for long if a connection cannot be established.

      SUNRPC: receive buffer size estimation values almost never change · 53bc19f1
      Chuck Lever 提交于
      Avoid unnecessary cache sloshing by placing the buffer size
      estimation update logic behind an atomic bit flag.
      
      The size of GSS information included in each wrapped Reply does
      not change during the lifetime of a GSS context. Therefore, the
      au_rslack and au_ralign fields need to be updated only once after
      establishing a fresh GSS credential.
      
      Thus a slack size update must occur after a cred is created,
      duplicated, renewed, or expires. I'm not sure I have this exactly
      right. A trace point is introduced to track updates to these
      variables to enable troubleshooting the problem if I missed a spot.

         - Keep nfsd clients from unnecessarily breaking their own

           Note this requires a small kthreadd addition. The result is Tejun
           Heo's suggestion (see link), and he was OK with this going through
           my tree.
      
         - Patch nfsd/clients/ to display filenames, and to fix byte-order
           when displaying stateid's.
      
         - fix a module loading/unloading bug, from Neil Brown.
      
         - A big series from Chuck Lever with RPC/RDMA and tracing
           improvements, and lay some groundwork for RPC-over-TLS"
