    Pull iomap updates from Darrick Wong:
     "The most notable changes are:
    
       - iomap no longer invalidates the page cache when performing a direct
         read, since doing so is unnecessary and the old directio code
         doesn't do that either.
    
       - iomap embraced the use of returning ENOTBLK from a direct write to
         trigger falling back to a buffered write since ext4 already did
         this and btrfs wants it for their port.
    
       - iomap falls back to buffered writes if we're doing a direct write
         and the page cache invalidation after the flush fails; this was
         necessary to handle a corner case in the btrfs port.
    
       - Remove email virus scanner detritus that was accidentally included
         in yesterday's pull request. Clearly I need(ed) to update my git
         branch checker scripts. :("
