| H A D | delayed-inode.h | 96d89923 Wed Aug 17 06:22:40 CDT 2022 Filipe Manana <fdmanana@suse.com> btrfs: store index number instead of key in struct btrfs_delayed_item
All delayed items are for dir index keys, so there's really no point of
having an embedded struct btrfs_key in struct btrfs_delayed_item, which
makes the structure use more space than necessary (and adds a hole of 7
bytes).
So replace the key field with an index number (u64), which reduces the
size of struct btrfs_delayed_item from 112 bytes down to 96 bytes.
Some upcoming work will increase the structure size by 16 bytes, so this
change compensates for that future size increase.
