[PATCH 0/2] btrfs: be less verbose on automatic bg reclaim

[Johannes Thumshirn <jth@kernel.org>]

From: Johannes Thumshirn <johannes.thumshirn@wdc.com>

BTRFS filesystems with active automatic block-group reclaim (this
especially hits zoned file systems where automatic block-group reclaim is
used for garbage collection) do a lot of log spamming, because every
relocated block group is accompanied by three prints at info level.

The first patch removes the info message that is only present with
automatic block group reclaim, we have a tracepoint right next to it so
there's no need for the message at all.

The second patch introduces a `verbose` parameter for
`btrfs_relocate_chunk()` and `btrfs_relocate_block_group()` to control if
we want to add printks or not. Automatic reclaim calls into
`btrfs_relocate_chunk()` setting `verbose` to false while the user-space
triggered balance code path sets `verbose` to true retaining the old
behaviour. 

Johannes Thumshirn (2):
  btrfs: remove redundant auto reclaim log message
  btrfs: don't print relocation messages from auto reclaim
