From 4c6646117912397d026d70c04d92ec1599522e9f Mon Sep 17 00:00:00 2001 From: Qu Wenruo Date: Wed, 15 Sep 2021 15:17:16 +0800 Subject: btrfs: rename btrfs_bio to btrfs_io_context The structure btrfs_bio is used by two different sites: - bio->bi_private for mirror based profiles For those profiles (SINGLE/DUP/RAID1*/RAID10), this structures records how many mirrors are still pending, and save the original endio function of the bio. - RAID56 code In that case, RAID56 only utilize the stripes info, and no long uses that to trace the pending mirrors. So btrfs_bio is not always bind to a bio, and contains more info for IO context, thus renaming it will make the naming less confusing.
