 "Five smb3 client fixes, mostly multichannel related:

   - four multichannel fixes including fix for channel allocation when
     multiple inactive channels, fix for unneeded race in channel
     deallocation, correct redundant channel scaling, and redundant
     multichannel disabling scenarios

   - add warning if max compound requests reached"
