From 2422547e99f99f952d1a37f26b63289f749d5fcd Mon Sep 17 00:00:00 2001 From: Johannes Thumshirn Date: Mon, 13 May 2024 18:01:43 +0200 Subject: btrfs: remove raid-stripe-tree encoding field from stripe_extent Remove the encoding field from 'struct btrfs_stripe_extent'. It was originally intended to encode the RAID type as well as if we're a data or a parity stripe. But the RAID type can be inferred form the block-group and the data vs. parity differentiation can be done easier with adding a new key type for parity stripes in the RAID stripe tree.
