Subject: bcachefs: Promotes should use BCH_WRITE_only_specified_devs
X-Git-Tag: v6.15-rc1~146^2~158
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8ff92a9e4e49fc1fa01e8d23462097ccbe90e3b6;p=thirdparty%2Flinux.git

bcachefs: Promotes should use BCH_WRITE_only_specified_devs

Promotes, like most other internal moves, should only go to the
specified target and not fall back to allocating from the full
filesystem.
