Subject: xfs: pass transaction to dfops reset/move helpers
X-Git-Tag: v4.19.0-rc0~14
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=76a3c33d438ba9c7cd3d1857d09933999d3875ad;p=thirdparty%2Fxfsprogs-dev.git

xfs: pass transaction to dfops reset/move helpers

Source kernel commit: ce356d64772f920f26cd6c1b02878a737a275638

All callers pass ->t_dfops of the associated transactions. Refactor
the helpers to receive the transactions and facilitate further
cleanups between xfs_defer_ops and xfs_trans.
