    writeback: Do not sort b_io list only because of block device inode · a8855990
    Jan Kara authored
    It is very likely that block device inode will be part of BDI dirty list
    as well. However it doesn't make sence to sort inodes on the b_io list
    just because of this inode (as it contains buffers all over the device
    anyway). So save some CPU cycles which is valuable since we hold relatively
    contented wb->list_lock.
