drbd_bm_write_lazy(9)

✨ NAME ✨

drbd_bm_write_lazy — write bitmap pages 0 to @upper_idx-1, if they have changed.

Okay bestie, this is the drbd_bm_write_lazy(9) page from the Kernel API Manual, and it's giving very targeted bitmap-writeout energy 💅. No cap, it only writes those bitmap pages if they've actually changed.

       );
