Subject: [PATCH 00/15] RAID/volumes code cleanups
Date: Fri, 17 May 2019 11:43:10 +0200	[thread overview]
Message-ID: <cover.1558085801.git.dsterba@suse.com> (raw)

This is preparatory work for RAID1C3, making use of the raid_attr table
that replaces the hand crafted if-else-if sequences and bit mask checks.
Pluging a new bg profile is easy on top of that, though there are still
some possible cleanups left.

There's one user-visible change, patch 2/15, where the balance filters
allow conversion to the RAID56 profiles with the minimum number of
devices. This is for consistency with mkfs/mount.

So this will work:

 $ mkfs.btrfs -d raid1 -m raid1 /dev/sda /dev/sdb
 $ mount dev/sda /mnt
 $ btrfs balance start -dconvert=raid5 -mconvert=raid5 /mnt

David Sterba (15):
  btrfs: fix minimum number of chunk errors for DUP
  btrfs: raid56: allow the exact minimum number of devices for balance
    convert
  btrfs: remove mapping tree structures indirection
  btrfs: use raid_attr table in get_profile_num_devs
  btrfs: use raid_attr in btrfs_chunk_max_errors
  btrfs: use raid_attr table in calc_stripe_length for nparity
  btrfs: use raid_attr to get allowed profiles for balance conversion
  btrfs: use raid_attr table to find profiles for integrity lowering
  btrfs: use raid_attr table for btrfs_bg_type_to_factor
  btrfs: factor out helper for counting data stripes
  btrfs: use u8 for raid_array members
  btrfs: factor out devs_max setting in __btrfs_alloc_chunk
  btrfs: refactor helper for bg flags to name conversion
  btrfs: constify map parameter for nr_parity_stripes and
    nr_data_stripes
  btrfs: read number of data stripes from map only once
