      dm bufio: change __GFP_IO to __GFP_FS in shrinker callbacks · 9d28eb12
      Mikulas Patocka authored
      
      
      The shrinker uses gfp flags to indicate what kind of operation can the
      driver wait for. If __GFP_IO flag is present, the driver can wait for
      block I/O operations, if __GFP_FS flag is present, the driver can wait on
      operations involving the filesystem.
      
      dm-bufio tested for __GFP_IO. However, dm-bufio can run on a loop block
      device that makes calls into the filesystem. If __GFP_IO is present and
      __GFP_FS isn't, dm-bufio could still block on filesystem operations if it
      runs on a loop block device.
      
      The change from __GFP_IO to __GFP_FS supposedly fixes one observed (though
      unreproducible) deadlock involving dm-bufio and loop device.
