      NFSv4: Fix problem with OPEN_DOWNGRADE · d530838b
      Trond Myklebust authored
      
      
       RFC 3530 states that for OPEN_DOWNGRADE "The share_access and share_deny
       bits specified must be exactly equal to the union of the share_access and
       share_deny bits specified for some subset of the OPENs in effect for
       current openowner on the current file.
      
       Setattr is currently violating the NFSv4 rules for OPEN_DOWNGRADE in that
       it may cause a downgrade from OPEN4_SHARE_ACCESS_BOTH to
       OPEN4_SHARE_ACCESS_WRITE despite the fact that there exists no open file
       with O_WRONLY access mode.
      
       Fix the problem by replacing nfs4_find_state() with a modified version of
       nfs_find_open_context().

      [PATCH] NFS: Introduce the use of inode->i_lock to protect fields in nfsi · dc59250c
      Chuck Lever authored
      
      
      Down the road we want to eliminate the use of the global kernel lock entirely
      from the NFS client.  To do this, we need to protect the fields in the
      nfs_inode structure adequately.  Start by serializing updates to the
      "cache_validity" field.
      
      Note this change addresses an SMP hang found by njw@osdl.org, where processes
      deadlock because nfs_end_data_update and nfs_revalidate_mapping update the
      "cache_validity" field without proper serialization.
      
      Test plan:
       Millions of fsx ops on SMP clients.  Run Nick Wilson's breaknfs program on
       large SMP clients.

      [PATCH] NFS: use atomic bitops to manipulate flags in nfsi->flags · 412d582e
      Chuck Lever authored
      
      
      Introduce atomic bitops to manipulate the bits in the nfs_inode structure's
      "flags" field.
      
      Using bitops means we can use a generic wait_on_bit call instead of an ad hoc
      locking scheme in fs/nfs/inode.c, so we can remove the "nfs_i_wait" field from
      nfs_inode at the same time.
      
      The other new flags field will continue to use bitmask and logic AND and OR.
      This permits several flags to be set at the same time efficiently.  The
      following patch adds a spin lock to protect these flags, and this spin lock
      will later cover other fields in the nfs_inode structure, amortizing the cost
      of using this type of serialization.
      
      Test plan:
       Millions of fsx ops on SMP clients.

      [PATCH] NFS: split nfsi->flags into two fields · 55296809
      Chuck Lever authored
      
      
      Certain bits in nfsi->flags can be manipulated with atomic bitops, and some
      are better manipulated via logical bitmask operations.
      
      This patch splits the flags field into two.  The next patch introduces atomic
      bitops for one of the fields.
      
      Test plan:
       Millions of fsx ops on SMP clients.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
