The scanner kicks in once speculative preallocation occurs and stops requeueing itself when no eofblocks inodes exist. The scan interval is based on the new 'speculative_prealloc_lifetime' tunable (default to 5m). The background scanner performs unfiltered, best effort scans (which skips inodes under lock contention or with a dirty cache mapping). Signed-off-by: Brian Foster<bfoster@xxxxxxxxxx> --- Looks good. Nice series. Reviewed-by: Mark Tinguely <tinguely@xxxxxxx> |
