btrfs: Remove btrfs_inode::delayed_iput_count
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 Signed-off-by: Nikolay Borisov <nborisov@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> [ reformat comment ] Signed-off-by: David Sterba <dsterba@suse.com>
