    Btrfs: autodetect SSD devices · c289811c
    Chris Mason authored Jun 10, 2009
    
    
    During mount, btrfs will check the queue nonrot flag
    for all the devices found in the FS.  If they are all
    non-rotating, SSD mode is enabled by default.
    
    If the FS was mounted with -o nossd, the non-rotating
    flag is ignored.
