      NFS: Return a real error code from mount(2) · fdc6e2c8
      Chuck Lever authored
      Don't filter the return code from the in-kernel rpcbind or NFS mount
      clients.  Return the real error code so that callers of the new NFS
      text-based mount API can apply a useful retry strategy.

      NFS: mount option parser chokes on proto= · fdb66ff4
      Chuck Lever authored
      The new text-based NFS mount option parsing logic doesn't recognize any
      valid transport protocols due to a silly mistake in the protocol token
      matching logic.  This prevents basic mount requests such as:
      
         mount.nfs server:/export /mnt -o proto=tcp
      
      from working with the new text-based NFS mount API.

      Doh! We can't use cancel_delayed_work_sync because we may have been called
      from an unmount that was being performed by nfs_automount_task.

      NFS: Fix the mount regression · e89a5a43
      Trond Myklebust authored
      This avoids the recent NFS mount regression (returning EBUSY when
      mounting the same filesystem twice with different parameters).
      
      The best I can do given the constraints appears to be to have the kernel
      first look for a superblock that matches both the fsid and the
      user-specified mount options, and then spawn off a new superblock if
      that search fails.
      
      Note that this is not the same as specifying nosharecache everywhere
      since nosharecache will never attempt to match an existing superblock.

      x86: be even more careful about checking the stack frame on dumping · 36ad4885
      Linus Torvalds authored
      lguest didn't initialize the kernel stack the way a real i386 kernel
      does, and ended up triggering a corner-case in the stack frame checking
      that doesn't happen on naive i386, and that the stack dumping didn't
      handle quite right.
      
      This makes the frame handling more correct, and tries to clarify the
      code at the same time so that it's a bit more obvious what is going on.
      
      Thanks to Rusty Russell for debugging the lguest failure-

      Do not use the ia64 clocksource on non-ia64 architectures · 3b2b64fd
      Linus Torvalds authored
      The HPET clocksource in drivers/char/hpet.c was written as generic code
      for ia64, but it is not yet ready to replace the native HPET clocksource
      implementations that the i386/x86-64 architectures use.
      
      On x86[-64], trying to register this clocksource results in potentially
      multiple hpet-based clocksources being registered, and if the ia64 one
      is chosen on x86_64 some users have experienced hangs.
      
      Eventually all three architectures may end up using the same code, but
      that is not the case right now.
