Subject: bcachefs: Run freespace init in device hot add path
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b1c945b3fd926ea121172eedc271f4b816b44387;p=linux.git

bcachefs: Run freespace init in device hot add path

Like in the recovery, and device add, we have to check if devices don't
have the freespace btree initialized - this was missed in the device hot
add path.
