From c501fef6deb1de13d45d22a3df32906adf17275b Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Mon, 13 Jun 2022 19:07:19 -0400 Subject: bcachefs: Pull out data_update.c This is the start of reorganizing the data IO paths. The plan is to also break apart io.c into data_read.c and data_write.c, and migrate_write will be renamed to the data_update path.
