    btrfs: Remove btrfs_inode::delayed_iput_count · c1c3fac2
    Nikolay Borisov 提交于
    delayed_iput_count wa supposed to be used to implement, well, delayed
    iput. The idea is that we keep accumulating the number of iputs we do
    until eventually the inode is deleted. Turns out we never really
    switched the delayed_iput_count from 0 to 1, hence all conditional
    code relying on the value of that member being different than 0 was
    never executed. This, as it turns out, didn't cause any problem due
    to the simple fact that the generic inode's i_count member was always
    used to count the number of iputs. So let's just remove the unused
    member and all unused code. This patch essentially provides no
    functional changes. While at it, also add proper documentation for
    btrfs_add_delayed_iput
