`subvol sync`: add implementation using SUBVOL_SYNC_WAIT ioctl

Open kdave opened this issue 11 months ago • 0 comments

Kernel 6.13 provides a new unprivileged ioctl to wait for subvolume cleaning (https://git.kernel.org/linus/6c83d153ed86eb17c46eafe4e78af4ce2071a05 "btrfs: add new ioctl to wait for cleaned subvolumes")

  • try the new ioctl first, if it does not exist fall back to the old SEARCH_TREE way
  • the new ioctl is not 1:1 functionality and does not know the full list of subvoulmes being cleaned; add an option to force the SEARCH_TREE ioctl that can do that
