    btrfs: Enhance message when a device is missing during mount · c5502451
    Qu Wenruo 提交于
    For a missing device, btrfs will just refuse to mount with almost
    meaningless kernel message like:
    
     BTRFS info (device vdb6): disk space caching is enabled
     BTRFS info (device vdb6): has skinny extents
     BTRFS error (device vdb6): failed to read the system array: -5
     BTRFS error (device vdb6): open_ctree failed
    
    This patch will print a new message about the missing device:
    
     BTRFS info (device vdb6): disk space caching is enabled
     BTRFS info (device vdb6): has skinny extents
     BTRFS warning (device vdb6): devid 2 uuid 80470722-cad2-4b90-b7c3-fee294552f1b is missing
     BTRFS error (device vdb6): failed to read the system array: -5
     BTRFS error (device vdb6): open_ctree failed
