From 7bb61e8c0e37fdf5684bc1fa1f6e0b5644cc7f75 Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Sun, 19 Jun 2022 23:03:07 -0400 Subject: bcachefs: Make IO in flight by copygc/rebalance configurable This adds a new option, move_bytes_in_flight, for configuring the amount of IO in flight by copygc/rebalance - users with many devices in their filesystem will want to increase this. In the future we should be smarter about this, but this is an easy improvement.
